ABSTRACT:
A polymerizable composition comprising a poly(3,4-dihydro-3-substituted-1,3 benzoxazine) and a reactive polyamine, wherein the polyamine is at least difunctional and its reactive groups are primary or secondary amine and wherein the poly(dihydrobenzoxazine) is the reaction product of about 1 equivalent of a primary amine, about 1 equivalent of a phenol and about two equivalents of formaldehyde. The compositions are useful as potting, encapsulating and laminating resins and as surface coatings.
