Method of producing dry polyvinyl acetate particles that are readily dispersible in water, are vinyl acetate monomer free and are useful for making polyvinyl acetate dispersion compositions that are low in odor, form clear dried films and may be used in adhesives, sealants, caulks and coatings. The method includes manufacturing an aqueous, e. g. water, dispersion of polyvinyl acetate containing polyvinyl alcohol; drying to remove volatiles by converting the dispersion to dry form under controlled temperature conditions and redispersing the dried polyvinyl acetate particles in an aqueous medium to form a polyvinyl acetate dispersion that is substantially free of vinyl acetate monomer.

A cyanoacrylate-based adhesive composition comprises 55-92% by weight of a 2-cyanoacrylate ester, preferably the ethyl ester, from 40-30% by weight of a vinyl chloride/vinyl acetate copolymer and not more than 25% by weight of a plasticizer (the plasticizer may be omitted entirely). The copolymer is preferably a vinyl chloride/vinyl acetate/maleic acid terpolymer. The adhesive compositions have greatly reduced adhesion to skin, not forming strong skin bonds for at least 30 seconds, in contrast to conventional cyanoacrylate adhesive compositions which form, within in about one second bonds strong enough to tear skin.

The present invention includes a high strength adhesive and includes a dispenser containing a high strength adhesive. The invention is an adhesive composition comprising: (a) water present in an amount of from about 40 percent to about 70 percent by weight; (b) polyvinyl acetate present in an amount of about 15 percent to about 35 percent by weight; (c) dextrin present in an amount from about 5 percent to about 35 percent by weight; and (d) starch present in an amount from about 0 percent to about 5 percent by weight; the adhesive having at least 30% by weight solids, having a paste-like consistency, and having a bond strength greater than about 2000 p. s. i. as measured by ASTM D-905. The adhesive of the present invention has a very workable consistency that is very much like room-temperature butter or shortening used in cooking.

An aqueous adhesive composition having pH of about 8 to 10 containing from about 25 to 75% by weight of water, the water having dispersed therein: A. from about 25 to 75% by weight of the composition, of a water-insoluble linear polymer of interpolymerized monoethylenically unsaturated monomers in amounts by weight based on the linear polymer: (1) from about 50 to 99% of an acrylic ester monomer of the formula ##STR1## or a mixture thereof, where R is H or methyl and R. sup. 2 is lower alkyl of 1 to 4 carbon atoms, (2) from about 0. 1 to 10% of acrylic acid or methacrylic acid, (3) from about 0. 1 to about 10% of a nitrogen containing monomer selected from the group consisting essentially of vinyl amines and salts thereof, vinyl ureido monomers, vinyl compounds having heterocyclic nitrogen containing groups, and mixtures thereof, and B. 0. 001 to 2% of a silane containing both alkoxy and epoxy functionalities.

This invention relates to polyvinyl acetate adhesives redispersible in hot and cold water in the dried film form. The adhesives comprise an emulsion of a polyvinyl acetate, an anti-coalescing polyvinylpyrrolidone and a non-volatile, water-soluble plasticizer for said anti-coalescing agent that is immiscible with the polyvinyl acetate resin, said plasticizer being present in amount to impart flexibility to the dried adhesive film and the ratio of polyvinyl acetate to anti-coalescing agent not exceeding about 8 parts by weight for each part by weight of agent.

An adhesive composition which comprises, for each 100 parts by weight thereof, an aqueous dispersion having pH of about 8 to 12 of the following components dispersed in 25 to 75 parts of water: A. from 25 to 75 parts by weight of water insoluble linear polymer containing the following interpolymerized unsaturated monomers in parts by weight based on the weight of the polymer: 1. at least 50 parts and up to 99 parts of an acrylate monomer containing from about 4 to 27 carbon atoms selected from alkyl acrylates, alkyl methacrylates, and mixtures thereof: 2. from about 0. 1 to 10 parts of a nitrogen monomer selected from vinyl amines and salts thereof; vinyl ureido monomers; vinyl compounds having heterocyclic nitrogen containing groups and halogen, hydroxyalkyl or aminoalkyl substituted derivatives thereof; amino and loweralkyl amino loweralkyl acrylates and methacrylates; and mixtures thereof; 3. from about 0. 1 to 25 parts of an acid selected from acrylic acid, methacrylic acid and mixtures thereof; B.

A water based thixotropic adhesive gel is disclosed which consists essentially of: water; partially hydrolyzed polyvinyl alcohol, or wherein a portion of the polyvinyl alcohol is replaced with polyvinylpyrrolidone; a water-soluble high viscosity thickening agent polymer which is compatible with the polyvinyl alcohol and which imparts thixotropic properties to the gel; a water-soluble plasticizer for the polyvinyl alcohol; and a watersoluble defoamer in proportion of ingredients so that the viscosity of the adhesive will break down when a flexible tube or squeeze bottle dispenser is finger-pressed and have a sufficiently low viscosity to allow for easy extrusion from an orifice having a diameter of about 0. 06 to 0. 12 inches. When pressure is released, after the desired amount of adhesive has flown out of the dispenser, the adhesive quickly reverts to very close to its original gel state so that it will not run on a vertical surface on porous and semiporous surfaces such as paper. An article of manufacture is also provided whereby the adhesive gel containing the above ingredients is in a flexible dispenser from which the adhesive can be dispensed by finger-pressure.

Adhesive compositions exhibiting fast cure time in solid form, e. g. in the form of an applicator crayon or glue stick. The adhesive exhibiting polymer of the composition is based on a mixture of critical amounts of high molecular weight polyvinylpyrrolidone polymer, with a lower molecular weight polyvinylpyrrolidone polymer, with water, an organic solvent, and a salt of a long-claim fatty acid, e. g. sodium stearate. Color indicators and other optional ingredients, e. g. mildewcide, can be included.
