<p>A prepolymer having an average molecular weight Mn 200 - 10,000 and an average molecular weight Mw 400 - 30,000 obtained by reacting at least one phosphinic acid derivative with at least one resin selected from epoxy resin, cyanate resin, an unsaturated polyester, vinyl ester, phenol resin, or a bismaleimide. The molecular weight is determined by GPC. A prepolymer having an average molecular weight Mn 200 - 10,000 and an average molecular weight Mw 400 - 30,000 obtained by reacting at least one phosphinic acid derivative of formula (R 1O)(R 2)P(O)-R 3 with at least one resin selected from epoxy resin, cyanate resin, an unsaturated polyester, vinyl ester, phenol resin, or a bismaleimide. The molecular weight is determined by GPC. R 1 and R 21-20C (aryl)alkyl, 1-20C (alkyl)aryl or 1-20C alkylarylalkyl (all optionally substituted);and R 3H or R 1. Independent claims are included for the following: (1) use of the prepolymer for producing a flame resistance polymer; and a flame resistance polymer comprising the prepolymer.</p> |
