A compound of the formula (1), ##STR1## WHEREIN R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are individually a hydrogen atom or a C.sub.1 -C.sub.20 alkyl group, A is a hydrocarbon residue, and n is an integer of 2 or 3, provided that when R.sub.1 is a methyl group and each of R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 is a hydrogen atom, the isopropenyl group ##STR2## is substituted at o- or m-position to the oxycarbonyl group ##STR3## which is useful as a crosslinking plasticizer for rubber.
化合物的公式为(1),其中R1、R2、R3、R4、R5、R6和R7分别为氢原子或C1-C20烷基,A为烃基残基,n为2或3的整数,但当R1为甲基且R2、R3、R4、R5、R6和R7均为氢原子时,异丙烯基##STR2##取代在氧羰基团##STR3##的o-或m-位置,该化合物可用作橡胶的交联增塑剂。
