    摘要： An electrooptical solid element comprises a formed resin composition comprising a low molecular polar substance having a Kerr type electrooptical effect, and an organic polymer substance compatible with the low molecular polar substance. The formed resin composition is prepared by a method such as melt mixing on rollers, or dissolution in a common solvent followed by evaporation of the solvent. This formed resin composition is prepared in various shapes such as a polygon, a film, a prism and a polygonal pole. At least a pair of electrodes are provided on the surfaces of the formed resin composition, and further at least one of the electrodes may can be made of a transparent material.

    摘要： A thermoplastic resin composition of excellent transparency and high impact strength is produced by causing methyl methacrylate and styrene monomers to undergo post polymerization in the presence of a conjugated diolefin polymer rubber latex containing at least 50 percent by weight of a conjugated diolefin monomer as the constituent of the rubber such as butadiene, wherein a polyethylene oxide of an average molecular weight of at least 100,000 has been added to the rubber latex either prior to or at the time of the post polymerization to cause the rubber latex to partly coagulate, thereby to prepare a graft polymer. The graft copolymer can be blended with methyl methacrylate-styrene copolymers.
