Use of di-(cyclohexylethylmethylol) phthalates or di- (ethylcyclohexylmethylol) phthalates as plasticizers for polyvinyl chloride

摘要

In a method of plasticizing polyvinyl chloride by adding a plasticizer to polyvinyl chloride, an improvement is provided wherein the plasticizer is a di-(cyclohexylethylmethylol) phthalate or a di- (ethylcyclohexylmethylol) phthalate of the formula ##STR1## wherein R is ethyl or hydrogen; R.sub.1 is methyl or hydrogen; and n is an integer of 0-2; and when n is 2, R is H and R.sub.1 is H; when n is 0, R is ethyl and R.sub.1 is H, and when n is 1, R.sub.1 is methyl and R is H; the two alcohol radicals being the same or different.
