Abstract:
A composition comprising (a) a polydithiocarbamate compound capable of forming a polymeric matrix with a cross-linking agent, and (b) a terminating agent for increasing water-solubility of the polymeric matrix so-formed, the terminating agent being selected from the group consisting of:i. non-emulsifying hydrotropes containing a sulfonate group,ii. non-emulsifying hydrotropes containing a sulfate group,iii. coupling agents selected from the group consisting of sulfates of ethoxylated alcohols, sulfates of propoxylated/ethoxylated alcohols, sulfates of ethoxylated phenols, sulfates of propoxylated/ethoxylated phenols, sulfates of ethoxylated amines, sulfates of propoxylated/ethoxylated amines, sulfonates of ethoxylated alcohols, sulfonates of propoxylated/ethoxylated alcohols, sulfonates of ethoxylated phenols, sulfonates of propoxylated/ethoxylated phenols, sulfonates of ethoxylated amines, sulfonates of propoxylated/ethoxylated amines, andiv. mixtures thereof;polydithiocarbamate compound comprising at least two groups represented by the formula --(OR.sup.1).sub.x NHC(:S)SR.sup.2, wherein R.sup.1 represents an alkylene group of 1 to 30 carbon atoms, R.sup.2 represents an alkali or alkaline earth metal group or an ammonium group, and x represents an integer of from 1 to about 250 independently selected for each of such groups such that the total of the integers is, on average, from 3 to 250.
