A process for preparing a surfactant, useful for dispersing tackifier resins in aqueous media, comprises reacting an αβ-unsaturated carboxylic acid or anhydride, or an ester thereof, with a terpene- or hydrocarbon-based resin to form an adduct, then reacting the adduct with a polyalkylene polyol to yield the surfactant. In a related embodiment, the surfactant is subsequently functionalized. Also disclosed are surfactants prepared using a disclosed process; compositions comprising a disclosed surfactant and a tackifier resin; aqueous dispersions comprising a disclosed surfactant; tackifier resin and water; adhesive compositions comprising a disclosed aqueous dispersion and a polymer latex; and pressure sensitive adhesive overlays prepared using a disclosed adhesive composition.

There are provided. alpha. -pinene epoxide polymers and. beta. -pinene epoxide polymers prepared by polymerizing monomeric. alpha. -pinene epoxide or. beta. -pinene epoxide dissolved in a non-polar solvent at a temperature ranging from between about -20. degree. C. and about -150. degree. C. in the presence of an inorganic, nonmetallic, fluoride catalyst, such as boron trifluoride and phosphorous pentafluoride, to obtain an optically active polymer useful as a tackifier in an adhesive composition.

A urethane-modified ester of rosin and a primary polyhydric alcohol has negligible hydroxyl content and is particularly useful as a polar tackifier in an adhesive composition made with a polar elastomer. The modified ester is prepared by reacting a rosin ester, for example, a rosin-pentaerythritol ester which contains some residual hydroxyl groups with a suitable isocyanate or diisocyanate.

The specification discloses a polyphenylene oxide delivery system for use in preparing an A-B-A block copolymer adhesive formulation having an increased service temperature. The delivery system comprises a preblend of polyphenylene oxide (PPO) resin having a T. sub. g within the range of from about 150. degree. to about 210. degree. C. and a B-block compatible resin. The PPO/B-block resin preblend enables introduction of more PPO into the composition thereby increasing the service temperature of the adhesive formulation.

There is provided a process for cationically polymerizing or co-polymerizing batchwise or continuously. alpha. -pinene by adding. alpha. -pinene either alone or in admixture with other terpene monomers, incrementally to a catalyst system comprising an aluminum halide and an antimony halide in the presence or absence of a (lower)alkyl, alkenyl or aralkyl halide in an inert solvent while controlling the temperature of reaction in the range of -30. degree. C. to +30. degree. C. , drowning the polymerization mixture in water, separating the organic phase therefrom, removing the solvent therefrom and recovering a solid polymer in good yield.
