Flame retardant resin compositions

摘要

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.
