PRODUCTION OF METAL COMPLEX OF VIII SUBGROUP HAVING UNSATURATED SILOXANE LIGAND, ADDITION OF SILICON COMPOUND HAVING SILICON-BONDED HYDROGEN ATOM TO ALIPHATIC MULTIPLE BOND AND COMPOSITION CONTAINING METAL COMPLEX

摘要

PURPOSE: To obtain the subject metal complex useful for the embossing of teeth of a person or an animal by reacting a compd. of a VIII subgroup metal having an unsaturated siloxane ligand and an aliphatic unsaturated organopolysiloxane. ;CONSTITUTION: The objective metal complex is obtained by reacting (A) a compd. of a VIII subgroup metal [pref., platinum (IV) halide] and (B) an organopolysiloxane comprising pref. a unit represented by the formula [wherein R is a 1-18C aliphatic saturated hydrocarbon; R¹ is an SiO-bond group represented by the formula: R²-CH=CH₂ (wherein R² is a 1-12C divalent hydrocarbon); (a) is 0, 1, 2 or 3; (b) is 0, 1, 2 or 3; a+b is not higher than 3; and at least three groups R¹ are provided per one molecule] and having a terminal aliphatic C-C-double bond and at least three SiC-bonded org. groups having at least three C-atoms.;COPYRIGHT: (C)1995,JPO
