    摘要: Processes for making a core and core-shell copolymers are provided herein. Processes for making crosslinked elastomeric core particles includes emulsion polymerizing, in the presence of a radical polymerization initiator, a polymerization mixture containing at least one ethylenic elastomeric monomer, at least one crosslinking agent, and at least one sulfur-containing additive of the formula I below, where R and Z are defined herein. The core-shell copolymers formed are useful for example as additives in polymer matrices such as for modifying impact strength and improving optical properties.

    摘要: The present invention relates to hybrid impact modifiers prepared by: either spray drying, coagulation, freeze coagulation or other known recovery methods of a mixture of a latex or slurry of standard impact modifiers and a slurry of a mineral filler, either simultaneous drying (by spray-drying, coagulation other known recovery possible methods) of (i) a latex or slurry of standard impact modifiers and of (ii) a slurry of a mineral filler, further to the coagulation or freeze coagulation, if any, there is a filtration and drying step to recover these hybrid impact modifiers as a powder. The host polymers to be impact modified, can be any thermoplastic. Advantageously it can be polyvinyl chloride (PVC), polyamide (PA), polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), thermoplastic polyesters such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycyclohexanedimethanol terephthalate, and polyolefins such as polyethylene (PE), polypropylene (PP), and any other matrix polymer which can be improved by an impact modifier.The present invention also relates to the use of said hybrid impact modifiers in thermoplastic polymers.The present invention also relates to a thermoplastic polymer containing said hybrid impact modifiers.The present invention also relates to hybrid impact modifiers having improved powder properties (flowability, lumping/caking resistance, segregation between the organic and the mineral parts).The present invention also relates to a thermoplastic polymer containing said hybrid impact modifiers with better dispersion homogeneities.
