    摘要: Nicely compatibilized polymer blends (i.e., "polyblends") exhibiting attendant physical properties which are generally improved over those intrinsically coincident with the individual polymeric ingredients therein are comprised, as fundamental Components therefor, of:(A) a substantial and effectively compatibilizing quantity of a graft or block inter- or copolymer of methyl methacrylate (i.e., "MMA") and/or equivalent acrylate monomer(s) on or with a synthetic or natural rubber elastomer (i.e., "EL") substrate as a basic component of the polyblend which is referred to hereinafter as an MMA-grafted rubber concentrate or, by way of simplified acronymical definition of same, a "GRC(MMA)" which is constitutionally substantially if not entirely free of any non-interpolymerized polymethylmethacrylate (i.e., "PMMA") or equivalent homopolymeric or copolymeric inclusions; plus(B) a significant quantity of a hydrocarbonaceous and/or halo-hydrocarbonaceous polymer, copolymer and/or interpolymer (including graft and block copolymer forms having elastomeric constituents) of styrene (i.e., "ST") and/or another alkenyl aromatic monomer; and, as an additionally optional ingredient,(C) another polymeric ingredient (such as, but without limitation, ABS or an ABS-type resin) that in physically blended admixture with a Component (B) polymeric ingredient results in a composite exhibiting attendant physical properties that are generally inferior in comparison to those intrinsically coincident with the individual polymeric ingredients therein.

    摘要: Membrane compositions useful in filtration and distillation applications are prepared by providing a glassy polymer composition (e.g., polystyrene) optionally having an amount of crosslinking and crazing the polymer composition in the presence of a monomer (e.g., methyl methacrylate) which can graft to said polymer composition. The membrane compositions so prepared comprise a microporous structure wherein the micropores can contain polymeric material. Alternatively, the surface region of the membrane composition and/or the surface region of the micropores has a polymeric material grafted thereto.
