Abstract

Vinyl chloride polymers are heat-stabilized by incorporating in the polymer, which may be plasticized, an epoxyurea of the formula: <FORM:0715202/IV (a)/1> in which Ar represents a substituted or unsubstituted aromatic radical. The polymer may be polyvinyl chloride or a copolymer of vinyl chloride and vinyl acetate. Specified stabilizers are ureido-phenyl-glycide ether and ureido-naphthyl-glycide ether. Plasticizers mentioned are dioctyl phthalate, dialkyl adipates and tricresyl phosphate.ALSO:Epoxyureas of the formula <FORM:0715202/IV (b)/1> where Ar represents an aromatic radical which may be substituted are made by reacting hydroxy-arylamines with a cyanate to form the desired hydroxyphenylurea and converting the latter with epichlorhydrin into the epoxyurea. In example (1) ureido-phenyl glycide ether is made by reacting epichlorhydrin and metahydroxyphenylurea made from meta-aminophenol hydrochloride and potassium cyanate; in example (2) para-aminophenol replaces meta-aminophenol whilst in example (3) a ureidonaphthyl glycide ether is obtained from 6-amino-1-naphthol in a manner similar to example (1) by way of hydroxynaphthylurea. The epoxyureas are used as stabilizers for vinyl chloride polymers.
