1. acrylic polymer compositions is used for providing the purposes of high Tg melt-mixing composition or apparatus for molded polymer products, and this acrylic polymer compositions comprises the melted blend of thermal plastic high polymer amount acryhic material HMWA and thermoplasticity low molecular weight propylene acid material LMWA;

  • At least the described HMWA of the 70%w/w of HMWA gross weight comprises (alkyl) acrylic acid alkyl ester polymer, and described (alkyl) acrylic acid alkyl ester polymer comprises the (C that is derived from of 80%w/w at least 1-C 8Alkyl) vinylformic acid C 1-C 12First polymer unit of alkyl ester monomer unit, described HMWA have 40k dalton to the daltonian weight-average molecular weight of 1000k;

    At least the described LMWA of the 70%w/w of LWMA gross weight comprises (alkyl) acrylic acid alkyl ester polymer, and described (alkyl) acrylic acid alkyl ester polymer comprises the (C that is derived from of 80%w/w at least 1-C 8Alkyl) vinylformic acid C 1-C 12Second polymer unit of alkyl ester monomer unit;

    Described LMWA has the entanglement molecular weight (M that represents with k dalton e) to the daltonian weight-average molecular weight of 250k, as long as HMWA has the Mw higher than LMWA, wherein said composition or product are chosen wantonly impact-resistant modified.
