TH17631EX - Styrene formulas Resin for casting And make a foam that has been improved - Google Patents

Abstract

The monovinylidene aerometric polymer resin formulation that may be optionally reinforced with rubber contains: a) a polymer matrix that may Choose rubber reinforcements and b) the volume of plasticizers. Soft solid (At room temperature and pressure) with a low molecular effect as a limnine polymer Alpha-Methyl Styrene And may choose to use vinyl lidene aerometric monomer that may be selected Other possible polymerization With an average mole weight of 1,000 to 70,000 volatile matter, volatile content up to 30 percent and at least a glass transition temperature of 25 ° C, the formulation has file-specific characteristics. Accept Surprisingly improved and has a toughness and hardness that does not diminish much. This invention It also includes a process for the production of polymeric foams. Further blending this invention with a potentially expandable monovinlidin anramatic polymer formula. Or it can form foam according to this invention and the resulting inflation agent and polymer film. The advantage is that this invention may be produced using only one CO2. Is the substance that causes this expansion
