“…Lucotte and Delfort 11 studied 1,2-bis(3-propargyloxyphenoxy)ethane blends with 1% of cupric chloride and cupric sulphate salts. They reported that the incorporation of 1% of cupric chloride and cupric sulphate significantly shifts the onset temperature to the lower region and concluded that the catalytic amount of such cupric salts was efficient to modify the thermal behaviour of the reaction.…”

Bispropargyl ether (BPE) of bisphenol-A was prepared. It was blended with 4,4'-bismaleimido diphenyl methane (BMI, 0.5:0.5 mol). The copper sulphate pentahydrate (CuSO 4 Á5H 2 O) was blended (1% w/w) separately with pure BPE and BPE-BMI blend and the materials were thermally cured. The structural characterization of the materials was done using a Fourier-transform infrared spectrophotometer. The curing behaviour of the materials was investigated using differential scanning calorimetry. The presence of copper salt in BPE shifted the curing temperature to lower temperature region. The presence of copper salt in BPE-BMI blend also decreased the curing onset temperature by approximately 15 C. The thermal property of the polymers was investigated using thermogravimetry. The incorporation of copper salt in BPE-BMI blend led to polymer with increased thermal stability.

“…Propargylic derivatives are obtained by the condensation of a propargyl bromide or chloride on a bisphenol in a basic medium 30,31 and in the presence of a phase transfer agent. First studied in the United States 32 , these compounds polymerise at 220°C with a very high polymerization enthalpy of (185 ± 8) kJ per function 31b,c,33 .…”

The introduction is a brief review of the characteristics desired for heat-resistant composite matrices, and the two possible approaches based on linear polymers and telechelic oligomers that can be cross-linked during use. Special attention is paid to cross-linkable oligomers, whose use currently poses fewer problems. The different structures in question, i.e. bismaleimides, bismaleimides (modified by cyanates or epoxies), bisnadimides, acetylene and propargylic compounds, are discussed in terms of chemistry (stability of oligomers, mode of polymerization, aging) and mechanical properties (ductility). Several solutions little used at the present time (semi-interpenetrated networks, molecular composites, polymerizable molecular assemblies, hyper branched oligomers and liquid crystal monomers, etc.) are discussed in terms of the future. There may be technical solutions for use up to 300°C, but industrial development is far from being resolved because of, among other things, the small market for these products.
