Abstract: Phosphorus-modified epoxy resins with an epoxide value of 0-1 mole/100g contain structural units derived from (A) polyepoxide cpds. with at least 2 epoxide gps./mol. ,and (B) phosphinic and/or phosphonic acid anhydrides, and also contain at least one phenolic antioxidant. Also claimed are moulded prods., coatings and laminates made from these resins. Pref. units (A) have a mean mol. wt. (Mn) of 150-4000, and are derived from polyepoxide cpds. with 2-6 epoxide gps./mol., pref. polyglycidyl ethers based on polyhydric phenols and/or hydrogenation prods. thereof and/or novolaks.

Abstract: Cycloolefin polymer molding composition of improved stability to chemical degradation. A cycloolefin polymer molding composition which comprises organophosphorus compounds of the formula IX R13-¢P(OR14)2!u (IX) of the formula X (X) or of the formula XI (XI) if appropriate in addition to other additives, shows an improved stability to chemical degradation. The organophosphorus compounds used according to the invention maintain the melt viscosity of the molding composition at the highest level (very small deviation from the starting value). They furthermore lead to the best initial colors of test specimens and to a relatively low change in color after kneading experiments.

Abstract: A cycloolefin polymer moulding composition containing organophosphorus compounds of the formula IX R -[P(OR )2]n (IX), of the formula X or of the formula XI optionally in addition to other additives, exhibits improved stability to chemical degradation. The organophosphorus compounds used according to the invention preserve the melt viscosity of the moulding composition at the highest level (least deviation from the initial value). They also result in the best initial colours of the test specimens and in a smaller colour change after compounding (kneading) experiments.

The invention furthermore relates to a process for the preparation of compounds of the formula (I) and to their use for stabilizing plastics, in particular polymerization plastics.
