<p>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.</p> |
