| 摘要 |
Resin compositions comprising flame retardant materials obtained by heating phosphonic acid salts at temperatures above 200° C., have excellent properties and exhibit manageable curing behavior. Laminates, composites, molded articles and the like, which have excellent flame retardant properties and physical characteristics, are readily prepared from the resin compositions of the invention. |
