Synthesis of polyurethane-polysiloxane graft copolymer using uniform-size poly(dimethylsiloxane) with a diol end group

A series of uniform-size poly(dimethylsiloxane)s (PDMS) containing a diol end group were synthesized by hydrosilylation of PDMS containing a silane end group with 3-allyloxy-1,2-propanediol. The polyurethane-polysiloxane graft copolymer was then synthesized by two different methods: polyaddition of...

Description
Summary:A series of uniform-size poly(dimethylsiloxane)s (PDMS) containing a diol end group were synthesized by hydrosilylation of PDMS containing a silane end group with 3-allyloxy-1,2-propanediol. The polyurethane-polysiloxane graft copolymer was then synthesized by two different methods: polyaddition of uniform-size PDMS having a diol end group with 4,4′-diphenylmethanediisocyanate (MDI), followed by chain extension with 1,4-butanediol (BD); and polyaddition of BD and MDI, followed by chain extension with uniform-size PDMS having a diol end group.
