Abstract
Abstract WHEREIN R1, R2 and R3 are selected from the group consisting of allyl, alkyl having from 1 to 18 carbon atoms and cycloalkyl having from 6 to 18 carbon atoms, at least one and no more than two of R1, R2 and R3 being allyl and provided that only one of R2 and R3 may be allyl, are useful as plasticizers for halogencontaining vinyl resins.
