摘要:
The invention is a poly(arylcyclobutene) comprising arylcyclobutene moieties connected by a bridging member, wherein the bridging member is (a) a direct bond, (b) a polyvalent inorganic radical or (c) a polyvalent organic radical which contains (1) one or more heteroatoms comprising oxygen, sulfur, nitrogen or phosphorus or (2) one or more aromatic radicals, and wherein one or more cyclobutene rings are fused to one of the aryl rings.
