  • High gloss rubber modified monovinylidene aromatic polymers produced by a mass polymerization process
    Patent number: 7115684
    Abstract: The present invention relates to a mass polymerized rubber-modified polymeric composition comprising a continuous matrix phase of a polymer of a monovinylidene aromatic monomer, and optionally, an ethylenically unsaturated nitrile monomer, and rubber particles produced from a functionalized diene rubber.
    Type: Grant

  • Flow carbonate polymer blends
    Patent number: 6306962
    Abstract: Disclosed is a polymer blend composition containing an aromatic carbonate polymer and a rubber-modified monovinylidene aromatic copolymer comprising a star-branched rubber and optionally, a linear rubber. The polymer blend compositions according to the invention have a desirable balance of processability and when molded, impact strength.

  • Rubber modified monovinylidene aromatic polymer compositions
    Patent number: 6211298
    Abstract: The present invention is an improved rubber-modified polymeric composition comprising: (a) a continuous matrix phase comprising an interpolymer of a monovinylidene aromatic monomer and an ethylenically unsaturated nitrile monomer; and (b) from 5 to 40 weight percent, based on the total weight of said polymeric composition, of a rubber in the form of discrete rubber particles dispersed in said matrix, wherein the dispersed rubber particles comprise: (1) at least 33 weight percent based on the total rubber content, of a mass rubber particle component having a volume average particle diameter of from 0.15 to 0.40 micron; (2) from 15 to 67 weight percent based on the total rubber content, of a small-particle emulsion rubber component having a volume average diameter of from 0.05 to 0.30 micron; and (3) from 0 to 35 weight percent based on the total rubber content, of a large emulsion particle rubber component having a volume average diameter of from greater than 0.30 to 2.

  • Salts of alkali metal anions and process of preparing same
    Patent number: 4107180
    Abstract: Compounds of alkali metal anion salts of alkali metal cations in bicyclic polyoxadiamines are disclosed. The salts are prepared by contacting an excess of alkali metal with an alkali metal dissolving solution consisting of a bicyclic polyoxadiamine in a suitable solvent, and recovered by precipitation. The salts have a gold-color crystalline appearance and are stable in a vacuum at -10.degree. C. and below.
