Abstract:
Thermoplastic resin polymer compositions having a block of random polysiloxane co- or terpolymer structure, such as substituted phenyl-terminated polysiloxane co- or terpolymers having the general structure: provide improved flame resistance, optical clarity, and better low-temperature impact strength compared to conventional blends, additives, and copolymers. The substituted phenyl terminated polysiloxanes may be used to make various polysiloxane-thermoplastic resin polymer and polymer blends, as well as articles including such polysiloxane-thermoplastic resin polymer and blends.
Abstract:
Disclosed herein is a polyorganosiloxane having the structure of Formula I: wherein, Ri and R2 are independently a hydrocarbon radical, an unsaturated radical, an alkoxy radical, an aryl radical or an alkenyloxy radical. R3 is an organic UV absorbing group, R4 independently is a direct bond, hydrocarbon radical optionally substituted with oxygen and nitrogen, or a group of Formula 11(a) or Formula 11(b) wherein A and B are a hydrocarbon radical, 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 1 to 50. The polyorganosiloxane is used to make various copolymers or polymer blends. A variety of articles can be made using the polysiloxane described as a polymer blend or copolymer.
