    • PURPOSE:To decrease the difference in sp. gr. from a liquid crystal and to lower a settling speed so as to prevent the settling and flocculating of particulates and to uniformalize the liquid crystal layer of the device by using high-polymer particulates of specific grain sizes for the liquid crystal layer. CONSTITUTION:The liquid crystal layer consists of a compsn. essentially consisting of the high-polymer exclusive of high polymers having cyanoalkyl groups) particulates of 0.01 to 1mum average grain size and a liquid crystal material. The particulates of the resins produced by polymn. methods, such as emulsion polymn., pearl polymn., mass polymn. and soln. polymn., of acrylic resins, methacrylic resins, etc., or the fine powders obtd. by pulverizing these particulates are usable as the above-mentioned high-polymer particulates. The liquid crystal is preferably a nematic liquid crystal, smectic liquid crystal and cholesteric liquid crystal. The liquid crystal is mixed with the high-polymer particulate or the high-polymer particulates are dispersed in the liquid crystal and spacers are mixed therewith. The mixture is then applied on electrode surfaces and the electrodes are stuck thereon, by which the capacitor-type liquid crystal device is obtd.

    • PROBLEM TO BE SOLVED: To provide a polymer molded product obtained by crosslinking a crosslinkable polymer, wherein deterioration in mechanical properties by heat is sufficiently suppressed.
      SOLUTION: The polymer molded product is hardened by actions of a peroxide crosslinking agent and a co-crosslinking agent. The rate of change of tensile strength (MPa) values measured according to ASTM D 638 before and after a thermal deterioration test conducted under a condition described below (i.e. the ratio of the difference between the tensile strength after and before the test and the tensile strength before the test) is from -55% to 0%. The thermal deterioration test is conducted by using a test piece punched out into a dumbbell shape No. 3 according to JIS K6251 and treating the test piece in a Geer oven at 250°C for 70 hr.
