Abstract: The invention relates to composite polymer modifiers for thermoplastic resins, and especially for polyvinyl chloride (PVC). The composite modifier is an intimate blend of mineral filler and polymeric process aid, which is formed by the co-powderization of aqueous emulsions, suspensions or slurries of one or more mineral filler(s) and process aid(s). The resulting composite modifier provides more effective modification of the thermoplastic resin than by the use of the dried components formed separately. The composite modifier may also contain other co-powderized components such as impact modifiers, for additional benefits.

Abstract: Evaporation of water from an aqueous dispersion of a solid peroxide such as benzoyl peroxide is retarded by the incorporation of carboxylic acid salt. The carboxylic acid salt renders the aqueous dispersion less susceptible to explosive decomposition when exposed to external triggering events such as impact, heat, friction or contamination, yet does not interfere with the ability to achieve and maintain a stable, small particle size dispersion having desirable viscosity and flow properties.
