Abstract:
There is described a polysiloxane having the structure: wherein R1, R2, and R3 are independently a hydrocarbon radical, an unsaturated radical, an alkoxy radical, an aryl radical or an alkenyloxy radical, R4 is independently a direct bond or hydrocarbon radical optionally substituted with oxygen and nitrogen, R5 is independently a hydrogen, a halogen, an aliphatic group having from 1 to 6 carbon atoms, an aromatic group having 6 to 8 carbon atoms, an alkoxy group having from 1 to 6 carbon atoms, or an aryloxy group, R6 is independently a hydroxyl group, an amine group, an acid chloride group, or a sulfonyl halide group, x is from 1 to 300; y is from 0 to 50; and z is from 0 to 50. The polysiloxane is used to make various copolymers and polymer blends. A variety of articles can be made using the polysiloxane described as a polymer blend or copolymer.
