Abstract: It is an object of the invention to improve the adhesive property of a curable composition mainly comprising a reactive silyl group-containing saturated hydrocarbon polymer when applied to various adherends and to improve the weathering-resistant adhesive property of said composition when applied to various glass products, in particular heat ray-reflecting glass products.The present invention relates to a curable composition which comprises (A) a saturated hydrocarbon polymer containing at least one silicon-containing group having a hydroxyl group or hydrolyzable group bound to the silicon atom and capable of crosslinking by forming a siloxane bond, (B) a silane coupling agent and (C) a compound containing, within the molecule thereof, an unsaturated group capable of polymerizing upon reaction with atmospheric oxygen and/or a photopolymerizing substance.

Abstract: A substrate of electrode for liquid crystal which comprises a substrate film for liquid crystal comprising an aromatic polyester or a polycarbonate which contains, as a bisphenol component, at least one selected from the group consisting of 1,1-bis(4-hydroxyphenyl)-alkylcycloalkane, 1,1-bis(3-substituted-4-hydroxyphenyl)-alkylcycloalkane and 1,1-bis(3,5-substituted-4-hydroxyphenyl)-alkylcycloalkane, and a transparent electrode for liquid crystal which is provided on at least one surface of the film. It has a high heat resistance, a low retardation and a low variation of the retardation thereof with heating.

Abstract: A transparent film having birefringence comprising an amorphous aromatic polymer as a main component is disclosed. The film is produced by uniaxially stretching a film of an amorphous aromatic polymer. The film exhibits high transparency, high heat resistance, and heat distortion resistance, and its birefringence does not undergo changes with time.

Abstract: An aromatic polyester film containing about 0.05 to 0.5% by weight, based on the weight of aromatic polyester resin, of a Group ITA alkaline earth metal orthophosphate powder composed mainly of particles having a particle diameter of about 1 to 10 .mu.m.

Abstract: A new polyimide film which contains 30 to 800 ppm of titanium based on the weight of the film, and a process for producing a new polyimide film which comprises introducing an organic titanium compound substance into the film-forming polyimide resin prior to the casting step. This process enables one to control the film surface forming process and improve directly the adhesive properties of the film.

Abstract: A multilayer film comprising an aromatic polyester layer and a silicone resin layer formed on at least one surface of the aromatic polyester layer. The multilayer film has excellent transparency, heat resistance, dimensional stability, mechanical strength and optical property and an improved solvent resistance, and is useful as a material of a liquid crystal display panel.

Abstract: A molding article comprises a molding of an aromatic polyester comprising an aromatic dicarboxylic acid and a bivalent phenol compound on which a layer of a metal or a metal oxide is deposited. The molding article has excellent heat resistance, transparency and surface resistance.

Abstract: A curable composition comprising an organic polymer containing at least one hydrolyzable a group attached to the silicon per polymer molecule and having a molecular weight within the range of 300 to 15,000, wherein a curing catalyst comprising tin II salt of organic carboxylic acid and/or lead II salt of organic carboxylic acid is used in combination with an acid material and/or a basic material, thereby unexpectedly improving the set resistance thereof. The composition may be utilized as a sealant which cures upon exposure to moisture to form a rubber like substance having improved set resistance.

Abstract: A room temperature curing composition comprising a polyoxyalkylene polymer having a silicon-containing hydrolyzable group and a hydrolyzable silicon compound as a stabilizer, which is stable in a closed system and is curable by exposure to moisture. The stabilizer has a higher hydrolysis reactivity than the polyoxyalkylene polymer and serves as a dehydrating agent, and therefore the storage stability can be remarkably improved.

Abstract: Compositions curable upon exposure to atmospheric moisture at room temperature comprising (a) organic polymer having at least one hydrolyzable silicon-containing group in the molecule and having a molecular weight from about 500 to 15,000 and (b) a photocurable substance.

Abstract: Disclosed is a resinous composition having excellent discoloration, processability, heat resistancy and durability comprising,A. 100 parts by weight of an aromatic polyester having the general formulae (I) and (II) ##STR1## B. 0.01 to 5 parts by weight of a phosphoric compound, and C. 0.01 to 0.1 part by weight of a carboxylic acid metal salt. Also disclosed is a process for producing shaped articles, the improvement which comprises adding the additives stepwise to the aromatic polyester.
