Abstract (en)
[origin: US5811486A] PCT No. PCT/DE96/00003 Sec. 371 Date Jul. 25, 1997 Sec. 102(e) Date Jul. 25, 1997 PCT Filed Jan. 2, 1996 PCT Pub. No. WO96/23018 PCT Pub. Date Aug. 1, 1996For better flame-retardant finishing and better workability of an epoxy-anhydride reaction resin system, it is proposed to supplement the reaction resin system with phosphonic semi-ester as additional reactive constituents. These are produced by conversion of phosphonic acid anhydride with single-valent or multi-valent alcohols. As a result of the selection of the alcohol constituent, property features of the molding material modified therewith that are already advantageous can be designationally set without thereby negatively influencing the hardening characteristic. Even with slight parts of phosphonic acid semi-ester, shaped members manufactured therefrom exhibit an adequate flame-retardant behavior given an otherwise unmodified property profile.
