Patent ID: 6933337

Claim:
A liquid plastisol comprising A) particles of a dispersion grade polymer selected from the group consisting of homopolymers and copolymers of vinyl chloride, the particles having an average size of less than 10 microns; B) from 10 to 100 weight percent, based on the weight of said polymer, of a plasticizer composition comprising 1) a diester corresponding to formula (I) R 1 C(O)OR 2 O(C))CR 3 ; I 2) a diester corresponding to formula (II) R 1 C(O)OR 2 O(O)CR 1 ; and II 3) a diester corresponding to formula (III) R 3 C(O)OR 2 O(O)CR 3 III wherein R 1 is at least one radical selected from the group consisting of phenyl and alkyl-substituted phenyl, R 2 is a divalent radical of the formula —R 4 (OR 4 )—, R 3 is an alkyl radical containing from 3 to 21 carbon atoms, R 4 is an alkyl radical containing m 2 to 4 carbon atoms, m represents 0 or the integer 1 or 2 and the molar ratio of R 1 to R 3 radicals is from 3:1 to 12:1, and C) at least one monoester exhibiting a formula selected from the group consisting of R 1 C(O)OR 2 OH and R 3 C(O)OR 2 OH and said monoester constitutes up 5 weight percent of said plasticizer composition.
