Polysilylether: A Degradable Polymer from Biorenewable Feedstocks

Abstract

The synthesis of polysilylethers (PSEs) using amonomer derived from abiorenewable feedstock is reported. The AB-type monomer was synthesized from undecenoic acid through hydrosilylation and reduction, and the polymerization was catalyzedbyearth-abundant metal salts.High-molar-mass products were achieved, and the degree of polymerization was controlled by varying the amount of an AA-type monomer in the reaction. The PSEs possess good thermal stability and al ow glass-transition temperature (T g %À67 8 8C). To demonstrate the utility of the PSEs,p olyurethanes were synthesized from low-molar-mass hydroxy-telechelic PSEs.
