Abstract
There is provided a method of synthesizing and using 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 in solution; and applying the segmented copolymer in solution to one or more surfaces via spray coating directly from the solution with the segmented copolymer, wherein the segmented copolymer formed has a high flexibility at an environmental temperature of down to about −100 degrees Celsius.
