Claims
- 1. An expandable polymeric composition comprising (a) a reaction product of vinylidene chloride and an .alpha.,.beta. ethylenically unsaturated silane and (b) a volatile blowing agent.
- 2. The composition of claim 1 in which said reaction product includes from 1-99% by weight of a copolymerizable monmer selected from the group consisting of vinyl functional monomers, alkyl esters of acrylic and methacrylic acid, ethylenically unsaturated mono- and dicarboxylic acids, and mixtures thereof.
- 3. The composition of claim 1 in which said silane is present in an amount of from 0.005 to 5.0% on a mole basis in the reaction product.
- 4. The composition of claim 1 further including from 1-2% by weight of an additional polymer selected from the group consisting of copolymers of ethylene and vinyl acetate, copolymers of styrene and acrylonitrile, copolymers of ethylene and methyl acrylate, polyolefins, and mixtures thereof.
- 5. The composition of claim 3 in which said silane is .gamma.-methacryloxypropyl trimethoxy silane.
- 6. The composition of claim 2 in which said vinylidene chloride comprises from 1 to 99.9% by weight of said reaction product.
- 7. The composition of claim 5 in which said reaction product comprises 93.87% vinylidene chloride, 6.0% methyl acrylate and 0.13% .gamma.-methacryloxypropyl trimethoxysilane.
