POLYMERS CONTAINING HEAT LABILE COMPONENTS ADSORBED ON POLYMERIC CARRIERS AND METHODS FOR THEIR PREPARATION

摘要

Compositions containing polymers and one or more heat labile and/or incompatible components adsorbed on carrier materials are provided. The heat labile components include materials that are inactivated, that volatilize, decompose, or undergo a chemical reaction or transformation at the polymer's processing temperatures (heat labile biocides). Incompatible components are materials that generally react or form gels or precipitates upon mixing. The carrier materials generally include inorganic or organic porous materials capable of remaining solid during processing temperatures. Methods for preparing the polymer compositions are provided.
