PP/PMMA block copolymers by combination of ATRP and metallocene catalysis

PP-b-PMMA has been synthesized by a combination of metallocene catalysis and the controlled radical polymerization technique ATRP. Cp2ZrCl2/MAO and (Me4CP)SiMe2(N-tert-Bu)TiCl2/MAO were used for the synthesis of atactic polypropylene. By a series of chemical modifications pp macroinitiators for the ATRP polymerization of MMA were synthesized. The PP-b-PMMA with polydispersities from 1.8-2.8 and an M-n ranging from 8 to 26 kg/mol was characterized by H-1-NMR,SEC and DSC.
