Abstract: A silane coupling agent is obtained from high-temperature heat distillation reaction of a silane coupling agent having a customary amic acid structure group. Dealcoholization reaction takes place between the carboxylic acid group and the alkoxysilyl group in the structure to induce intramolecular crosslinking. The crosslinked polymer component exerts a remarkable adhesion promoting effect.

Abstract: A hydrosilylation method is provided. In this hydrosilylation method, silylation of the carbon atom other than the terminal carbon atom and generation of the by-product isomer by internal migration of the double bond are suppressed without sacrificing the hydrosilylation reactivity, even if an olefin compound having tertiary amine atom which can be a catalyst poison was used. In the hydrosilylation, an olefin compound having carbon-carbon unsaturated bond, and a compound having hydrogensilyl group are reacted in the presence of an acid amide compound, a nitrile compound and an aromatic hydroxyl compound, or an organoamine salt compound, by using catalytic action of platinum and/or its complex compound.

Abstract: A coating composition comprising a hydrolyzable silyl-containing (meth)acrylic copolymer which is obtained from copolymerization of an alkyl (meth)acrylate with a silane compound having a long-chain alkylene linker between a hydrolyzable functional group and a radically polymerizable unsaturated group, and an organometallic catalyst is low-temperature curable and isocyanate-free. Even though the silane content is increased for coating hardness, the composition maintains alkali resistance and has good adhesion and solvent resistance when applied onto substrates.
