Abstract
Excellent physical and chemical properties are achieved from cured blends of silicone polymer with organic polymers, without the use of a compatibilizer. The silicone polymer may be a high molecular weight silicone (gum) polymer or a lower molecular weight silicone polymer (LSR) formulated with a catalyst for heat cure, or a silicone polymer designed as a moisture curing Room Temperature Vulcanizing (RTV) formulation. The organic polymer may be derived from a monoolefin or from a conjugated diolefin monomer, vinyl-substituted aromatic monomer such as styrene may also be included.
Claims22
A blend composition comprising
- a. at least one silicone polymer;
- and
- b. at least one organic polymer comprising residues derived from at least one olefin monomer;
- with the proviso that the blend composition does not comprise a polyfunctional compatibilizer having an ethylenically unsaturated functional group and a group selected from hydroxy, alkoxy, carboxy, ester, amide, and halogen.
