Abstract:
The invention relates to functionalized bimodal butadiene-methylmethacrylate impact modifiers. The impact modifiers are especially useful in blends of engineering resins, particularly where the blend contains both functional and non-functional resins. Polycarbonate (PC)/polyethylene terephthalate (PET) blends using the functionalized bimodal butadiene-methylmethacrylate impact modifiers of the invention have excellent low temperature impact performance.

Claim (Index 11):
An impact modified polymer alloy composition comprising:\n a) a functional polymer, b) and at least one non-functional polymer, c) functionalized core-shell impact modifier particles having substantially uniform composition and consisting of: 1) an elastomeric core comprising siloxanes or silicon containing elastomers, at least one polymer selected from the group consisting of butadiene and butadiene-styrene polymers, and optionally crosslinking monomer, and 2) one or more functionalized hard outer polymer shell comprising one or more functional monomers selected from the group consisting of glycidyl(meth)acrylate, maleic anhydride and mixtures thereof, and one or more non-functional monomers selected from the group consisting of styrene, methyl methacrylate, ethyl acrylate, and mixtures thereof, and wherein said hard outer polymer shells have a Tg of from 40 to 150\u00b0 C.,\n wherein said impact modifier particles have a bimodal particle distribution which is not the result of a blend, said bimodal particle distribution containing 5 to 40 weight percent of particles having an average particle size of from 30 nm to less than 200 nm, and 60 to 95 weight percent of particles having an average particle size of from 200 nm to 1000 nm, and \n d) optionally one or more of glass beads, polymer beads, glass fibers, carbon nanotubes, anti-oxidants, stabilizers, pigments, dyes, or lubricants.
