TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The carboxylic acid metal salt is tin carboxylate, lead carboxylate, bismuth carboxylate, potassium carboxylate, calcium carboxylate, barium carboxylate, titanium carboxylate, zirconium carboxylate, hafnium carboxylate, vanadium carboxylate, manganese carboxylate, iron carboxylate, cobalt carboxylate, nickel carboxylate, and/or cerium carboxylate, preferably bivalent tin carboxylate. The carbon atom adjacent to carbonyl group in acidic radical of carboxylic acid metal salt is quaternary carbon. Preferred Composition: The curable composition further contains an amine compound.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The organic polymer is polyoxyalkylene group polymer, saturated hydrocarbon group polymer and/or (meth)acrylic ester group polymer. The polyoxyalkylene group polymer is polyoxypropylene group polymer. The organic polymer has structure of formula: -NR1-C(=O)- in principal chain.R1=hydrogen atom or (un)substituted organic group. EXAMPLE - Propylene oxide was polymerized in presence of zinc hexa cyano cobaltate glyme complex compound catalyst using polyoxypropylene diol having molecular weight of 2000 as initiator. Polypropylene oxide having number average molecular weight of 25500 was obtained. Methanol solution was added with respect to hydroxyl group of polypropylene oxide, and methanol was distilled off. Allyl chloride was further added and hydroxyl group of terminal was converted into allyl group. Unreacted allyl chloride was removed. Water (in weight parts) (300) and n-hexane (300) was mixed and stirred with obtained allyl-group terminal polypropylene oxide. Water (300) was further mixed and stirred with obtained hexane solution. Hexane was removed, and bifunctional polypropylene oxide having number average molecular weight of 25500 was obtained. The obtained polymer (100) and methyl dimethoxy silane (0.93) were reacted at 90degreesC for 5 hours using platinum vinyl siloxane complex to obtain methyl dimethoxy silyl group terminal polyoxypropylene group polymer. The obtained polymer (100), calcium carbonate CCR (surface treated colloid calcium carbonate) (120), TIPAQUE R-820 (titanium oxide) (20), SANSOCIZER DIDP (diiso decylphthalate) (55), Disparlon 6500 (thixotropy providing agent) (2), tinuvin 327 (ultraviolet absorber) (1), Sanol LS770 (optical stabilizer) (1), A-171 (2), A-1120 (N-((beta)-amino ethyl)-(gamma)-aminopropyl trimethoxy silane) (3), Basatic 10 (1.25) and 3-diethylamino propyl amine of neo decanoic acid (0.5) were mixed to obtain a curable composition. The amount of carbonyl group in acidic radical of carboxylic acid metal salt was 7.3 mmol with respect to 100 g of organic polymer. The curable composition contained 400 ppm of moisture content and had excellent adhesion.
