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.

Claim (Index 1):
A composite polymer modifier consisting of:\n a) from 99 to 1 weight percent of one or more inorganic mineral fillers and mixtures thereof, b) from 1 to 99 weight percent of one or more polymeric process aids wherein at least one of said one or more process aids is an acrylic copolymer having two or more different monomer units, said acrylic copolymer having 60 percent of one or more of acrylic and/or (meth)acrylic monomer units selected from the group consisting of methyl acrylate, ethyl acrylate, butyl acrylate, 2-ethyl-hexyl-acrylate, methyl methacrylate, ethyl methacrylate, and butyl methacrylate, and c) optionally from 0 to 80 weight percent of one or more polymeric impact modifiers, wherein said one or more polymeric impact modifier is selected from the group consisting of core-shell impact modifiers, and linear copolymer impact modifiers,\n wherein the total adds up to 100 weight percent, and wherein said composite polymer modifier is in the form of powdered, substantially homogeneously blended complex particles containing both polymer and inorganic mineral fillers in intimate contact, and wherein said composite polymer modifier is formed by a process comprising the steps of: \n a) blending aqueous solutions, dispersions, suspensions or emulsions of said one or more polymeric process aids with said one or more mineral fillers which may be in the form of either an aqueous dispersion or a dry powder, and optionally with an aqueous dispersion of said one or more impact modifiers to form a homogenous aqueous blend, and b) powderizing said aqueous blend to form said composite polymer modifier;\n wherein steps (a) and (b) occur sequentially or concurrently.
