B-STAGEABLE THERMOSETTABLE COMPOSITIONS,METHOD OF MAKING B-STAGEABLE THERMOSETTABLE COMPOSITIONS AND USES OF B-STAGEABLE THERMOSETTABLE COMPOSITIONS |
摘要 |
The invention is concerned with B Stageable thermosettable compositions capable of producing a thermoset having a high service temperature comprising at least one polyepoxide and at least one linear anhydride monomer capable of forming a cyclopolymer in situ. The composition is useful in a two stage process; first to form a storage stable, flowable thermoplastic B stage intermediate by the free radical initiated vinyl polymerization of the linear anhydride in the liquid composition to a cyclic polymer and secondly to react the cyclic polymer with the poly epoxide to form a crosslinked high service temperature thermoset useful in the preparation of laminates, such as printed circuit boards, adhesives, and encapsulants. |
