FLAME-RETARDANT HALOGEN-CONTAINING UNSATURATED ALKYDS RESINS AND ARTICLES MADE THEREFROM

摘要

A halogen-containing unsaturated alkyd is synthesized by reacting a monobasic carboxylic acid and/or monohydric alcohol containing a post-halogenatable carbon-to-carbon double bond with an unsaturated polybasic carboxylic acid and a polyhydric alcohol and post-halogenating the resulting unsaturated alkyd. A flame-retardant unsaturated polyester resin composition comprising said halogen-containing un-saturated alkyd may be used for fabricating various shaped articles such as fame-retarded electrical laminates.
