Claims18
A method of stabilizing a biocide in a composition processed at elevated temperatures comprising:
- providing a composition comprising:
- (a) a matrix,
- (b) a biocide, and
- (c) an antioxidant, and
- processing the composition at a matrix processing temperature up to 250° C.,
- wherein the biocide is subject to thermal degradation at the matrix processing temperature and the antioxidant is present in an amount sufficient to stabilize the biocide such that the biocide exhibits thermal stability at the matrix processing temperature.
