Flame retardant aromatic polycarbonate resin composition and molded articles thereof

To an aromatic ring-bearing synthetic resin such as an aromatic polycarbonate resin or aromatic epoxy resin is added a minor amount of an organopolysiloxane which contains phenyl radicals and monofunctional siloxane units in a molecule wherein the contents of alkoxy radicals and hydroxyl radicals are each set at less than 2% by weight. Molded parts of the resin composition are flame retardant, optically transparent, and recyclable for reuse.

Flame retardant resin compositions

A polycarbonate composition comprising an aromatic polycarbonate resin and an organopolysiloxane having a specific structure is flame retardant, evolves no harmful gases upon combustion, and is molded into parts with optical transparency.

Flame retardant polycarbonate resin compositions

A resin composition comprising (A) an aromatic polycarbonate resin or aromatic epoxy resin and (B) a minor amount of an organosiloxane containing phenyl and alkoxy radicals is flame retardant and does not emit harmful gases when burned. It can be molded into parts having optical transparency.

Proposed is a method for the preparation of a monolithically integrated composite cured body consisting of a part of cured silicone rubber composition and a part of a silicone-epoxy resin composition firmly bonded together without using any primer or adhesive by first curing either one of the compositions in a metal mold and then bringing the other of the compositions into direct contact with the already cured part in the metal mold to be cured thereon. Firm bonding between the parts can be obtained when the silicone rubber composition is of the peroxide-curable or the hydrosilation-curable type and the silicone-epoxy resin composition comprises:

Composite body of silicone rubber and silicone-epoxy resin and method

Provided is a thermoplastic fluorosilicone resin of the average compositional formula (1):

Thermoplastic fluorosilicone resin and method of making

A novel curable organopolysiloxane-epoxy resin composition, which is capable of giving a cured body having excellent mechanical properties without the problem of adhesion to the metal mold, is proposed. The composition comprises: (a) an epoxy resin; (b) an organopolysiloxane containing vinyl groups; (c) an organohydrogenpolysiloxane as the crosslinking agent of the component (b); (d) a platinum compound as a catalyst for the hydrosilation reaction; and (e) a specific organic aluminum compound, such as tris(acetylacetonato) aluminum, each in a specified proportion.

Hydrosilation

A coating composition to form a coat on the surface of electrophotographic carrier which imparts excellent durability, moisture resistance and flowability to the carrier comprises:
