ABSTRACT:
An ungelled polymeric reaction product having a number average molecular weight of up to about 3000 and having a polydispersity of within 1.2 to 2.5 is prepared by a process involving the vinyl addition polymerization of a vinyl monomer component. At least 30 percent by weight of the vinyl monomer component is an active hydrogen-containing vinyl monomer, and the polymerization is conducted in the presence of an active hydrogen-containing polymer having a number average molecular weight of less than 3000.
