Synthesis of poly(silyl ester)s via hydrosilylation-based polymerization of AB monomers

Poly(silyl ester)s based on AB monomer systems were synthesized through transsilylation and hydrosilylation routes. Relatively faster propagation rates and higher degrees of polymerization were achieved when compared to polymerizations through AA/BB systems. Polymerizations through the hydrosilylation route reduced the monomer preparation difficulties, lowered the reaction temperatures to ambient temperature, and shortened the reaction times. The difficulties for silyl compounds with sterically bulky substituents to undergo hydrosilylation using the current catalyst system limited the polymerizations through AB monomer systems to the synthesis of poly(silyl ester)s with methyl side chain substituents.
