Abstract
A review is presented of the characteristics required for heat resistant composite matrices, with details of two possible approaches based on linear polymers and telechelic oligomers that can be crosslinked during use. Special attention is given to crosslinkable oligomers. The different structures studied are bismaleimides, bismaleimides modified by cyanates or epoxies, bisnadimides, acetylene and propargylic compounds. These are discussed in terms of chemistry (stability of oligomers, mode of polymerisation, ageing), and ductility. A discussion is presented of several little used solutions, i.e., semi-interpenetrated networks, molecular composites, polymerisable molecular assemblies, hyper-branched oligomers and liquid crystal monomers, etc., with reference to their future relevance. Despite the fact that technical solutions may be found for use of such materials up to 300 degrees C, the market is considered to be too small for these products to be further developed. 75 refs.
