Abstract:
There is provided a method of synthesizing a segmented copolymer that includes mixing one or more α,ω (alpha, omega) amine or α,ω (alpha, omega) hydroxyl terminated polysiloxane first soft segments having an average molecular weight of between about 2500 grams per mole to about 10,000 grams per mole, and one or more diisocyanate species, together to form a first reaction product; mixing the first reaction product and one or more low molecular weight diol or diamine chain extenders each having an average molecular weight of less than 400 grams per mole, together in a solvent to form a segmented copolymer; and, removing the solvent.
