Abstract
Polymers of the formula [(A.sub.n.sbsb.1 -R-D.sub.n.sbsb.2).sub.v P.sub.n.sbsb.3 ].sub.w Z.sub.n.sbsb.4 where A is a peroxy-containing group; R is a 2-4 valent aliphatic, cycloaliphatic or aromatic radical; P is a polyvalent polymeric residue; D is a carbonyl-containing connecting group; and Z is a terminal group, such polymers being useful with vinyl monomers in the formation of block and graft polymers.
