S. Demoustierchampagne et al., SYNTHESIS AND CHARACTERIZATION OF POLYMETHYLPHENYLSILANE-POLYSTYRENE BLOCK-COPOLYMERS, Journal of polymer science. Part A, Polymer chemistry, 31(8), 1993, pp. 2009-2014
Block copolymers of polymethylphenylsilane (PMPS) and polystyrene (PS)
have been successfully prepared by the condensation of alpha,omega-di
chloro-polymethylphenylsilane with polystyryl-lithium. These new mater
ials have been characterized by UV spectroscopy, Si-29-NMR, and size e
xclusion chromatography. These block copolymers show a good emulsifyin
g activity to compatibilize blends of the two homopolymers (PMPS and P
S).
