Novel silicone/polylactone graft copolymers, well suited as polymer composition additives, especially those destined for biomedical applications, have the average general formula: <IMAGE> (I) in which p is an integer or decimal ranging from 1.5 to 6, q is an integer or decimal ranging from 0 to 20, A is a divalent hydrocarbon having from 2 to 20 carbon atoms, n is an integer ranging from 3 to 12, m is an integer ranging from 2 to 25, the radicals R', which may be identical or different, are each hydrogen or C1-C4 alkyl, and R is a hydrocarbon having up to 24 carbon atoms. |
