Abstract
Styrene/ethyl methacrylate (SEMA) colloids were obtained by cocondensa tion at 77 K of the monomers with several metals such as Au, Pd, In an d Sn. The colloids were polymerized with 2,2'-azoisobutyronitrile and dibenzoyl peroxide as radical initiators at 60 degrees C for 3.5 h. A viscosity average molecular weight (10(4) < M(v) < 10(5)) was obtained depending upon the metal used,The particle size of these clusters dis persed in the copolymers ranges from 20 to 31 Angstrom. The metal clus ters are incorporated in the copolymers.
