CYCLIC OLEFIN-BASED RESIN MOLDING PRODUCT AND ITS PRODUCTION

Japanese Patent JP3945598

B2

PROBLEM TO BE SOLVED: To obtain the subject molding product capable of stably preserving a physiologically active substance, especially perfume, etc., for a long period of time, and gradually releasing it to the environment, by including a specific cyclic olefin-based resin and a physiologically active substance.
SOLUTION: This molding product is obtained by mixing (A) 100 pts.wt. of at least one cyclic olefin based resin selected from the group consisting of (i) an ethylene/cyclic olefin random copolymer obtained by polymerizing ethylene with a cyclic olefin of the formula ((n) is 0 or 1; (m) is 0 or a positive integer; (q) is 0 or 1; R1 to R18, Ra and Rb are each independently H, a halogen, a hydrocarbon, etc.), etc., (ii) a ring-opening polymer or copolymer of the cyclic olefin of the formula, etc., (iii) a hydrogenated substance of the component, (ii) and (iv) a graft modified substance of the component (i), the component (ii) or the component (iii) with (B) 0.01-50 pts.wt. of a physiologically active substance (preferably perfume) and molding. Preferably, the molding product further contains an ultraviolet light absorber and/or a heat stabilizer.
