ABSTRACT:
A polymerization initiator composition, comprising an azobisamidine salt represented by the general formula (1) ##STR1## wherein R.sup.1 and R.sup.2 independently represent an alkyl group or a cycloalkyl group, providing that R.sup.1 and R.sup.2 may together form an aliphatic ring, and Y represents --C(.dbd.NR.sup.3)--NH--R.sup.4 or a guanyl group represented by the formula (2) ##STR2## wherein R.sup.3 and R.sup.4 independently represent a hydrogen atom, an alkyl group, a substituted alkyl group, a cycloalkyl group, an allyl group, a phenyl group, or a substituted phenyl group, R.sup.5 represents a lower alkylene group optionally containing a substituent group, and R.sup.6 represents a hydrogen atom or a hydroxyalkyl group, and X represents a chlorine atom, a bromine atom, or a CH.sub.3 COO-- group, and a hydrophilic organic compound.
