A method of making oleochemical oil-based polyols by mixing an acid activated or acid leached clay, an epoxidized oleochemical oil, alcohol, and acid activated or acid leached clay so the epoxidized oleochemical oil reacts with said alcohol to form a oleochemical oil-based polyol, filtering out said clay, stripping off any excess alcohol, and recovering the oleochemical oil-based polyol.

Branched and cyclic N,N-dialkyldithiocarbamyl accelerators for the sulfur vulcanization of rubber have been found to generally perform as well as the corresponding straight chain N,N-dialkyldithiocarbamyl accelerators, but surprisingly do not produce detectable amounts of environmentally undesirable N-nitrosamines. The branched N,N-alkyldithiocarbamyl accelerators are generally represented by the formula: ##STR1## where R is a branched alkyl group, R' is an alkyl group which may or may not be branched or a cyclic alkyl group or an alkaryl or aryl group, X is another thiocarbamyl group of the same general structure, a primary alkylamino group, an alkylthio group, a 2-benzothiazyl group, or a metal ion, and n is an integer of from 1 to 6. The cyclic dithiocarbamyl accelerators of the invention are generally represented by the formula ##STR2## where X is another thiocarbamyl group of the same general structure, a primary alkylamino group, an alkylthio group, a 2-benzothiazyl group, or a metal ion, and n is an integer of from 1 to 6.

Amines are reacted with phosphorous trichloride to form N-dichlorophosphinoamines that are then reacted with a bisphenol in about equimolar amounts to provide polyphosphoramidite oligomers. The polyphosphoramidite oligomers are effective as stabilizers for polymers such as polyolefins, and form even more efficient stabilizer combinations with hydroxyphenylalkyleneyl isocyanurates.

3,6-di-t-butyl-2-naphthyl catechol phosphite is readily prepared by the reaction of catechol phosphorodichloridite and 3,6-di-t-butylnathphol in the presence of a trialkyl amine in a solvent. The 3,6-di-t-butyl-2-naphthyl catechol phosphite is an excellent stabilizer for polymers, including polypropylene, and forms synergistic combinations with hydroxyphenylalkyleneyl isocyanurates that provide excellent resistance to polymer breakdown during processing.

2,6-Di-t-butyl-4-substituted phenyl bis(3,6-di-t-butyl-2-naphthyl)phosphites, readily prepared by reacting together a phosphorodichloridite of a 4-substituted-2,6-di-t-butylphenol and a sodium salt of 3,6-di-t-butyl-2-naphthol, to form antioxidant and ultraviolet stabilizers that form particularly effective combinations with hydroxyphenylalkyleneyl isocyanurates to provide enhanced oven aging properties to organic materials subject to attack by heat and oxygen.

Tris (3,6-di-t-butyl-2-naphthyl) phosphite is a heat and hydrolysis resistant stabilizer for organic materials subject to heat and ultra-violet degradation, and in combination with hydroxy-phenylalkyleneyl isocyanurates, provides a useful synergistic combination for use in polymers, particularly hydrocarbon polymers including the poly(olefins).

Tetrakis(2,6-di-t-butyl-4-substituted phenyl)4,4'-substitutedbisphenyl diphosphites that are prepared from a hindered phenol and a non-hindered bisphenol have been found to be excellent stabilizers for organic materials subject to degradation, and form even more effective combinations with hydroxyphenylalkyleneyl isocyanurates, substantially and synergistically enhancing the stabilizing efficiency of the isocyanurate.
