Abstract:
Poly(benzoxazine) polymer are prepared by heating a benzoxazine compound in the presence of a (meth)acrylate copolymer having pendent tosylate groups, resulting in an interpenetrating polymer network of a poly(benzoxazine) and a crosslinked (meth)acrylate copolymer.
Abstract:
Novel benzoxazine - thiol adducts are described, which may be may be cured to produce compositions useful in coating, sealants, adhesive and many other applications.

Abstract:
The disclosure provides a catalyst for use with a benzoxazine resins which imparts accelerated curing at reduced temperatures. The catalyst is selected from elemental halogen or onium polyhalide compounds.
Abstract:
A curable benzoxazine composition is described wherein the benzoxazine is derived from an aryl amine having a b.p. > 200°C. The curable compositions are more thermally stable and have reduced weight loss and by-products upon cure.
Abstract:
A polymerizable composition is described comprising a benzoxazine, and a tosylate, which when thermolyzed, forms a (meth)acrylamide, a (meth)acrylate, a vinyl ketone, a vinyl ether or a styrenic compound.
