Fire-retardant polyurethane foams |
摘要 |
Production of urethane foams of increased fire resistance by mixing an ethylenic, e.g. allyl or vinyl, phosphorus compound with a polyol and polymerizing the polyol with polyisocyanate while simultaneously polymerizing the ethylenic phosphorus compound with a suitable catalyst to form an interpenetrating network of urethane polymer and phosphorus-containing polymer.
