Abstract
In this paper, the poly(4,4'-diethynyldiphenylmethane) is synthesised by the thermo-polyme-rization and catalysis polymerization (using (Ph3P)2PdCl2 as catalyst) of 4,4'-diethynyldiphen-ylmethane in bulk, and the copolymers of 4,4 -diethynyldiphenylmethane and phenylacetypene is also synthesised using (Ph3P)2 PdCl2 as catalyst. The density, the swellability and, the solubility parameter, Huggins parameter and the average molecular weight between crosslinks (Mc) of crosslinking products are measured. And the thermogravimetric analysis of crosslinking products and Infrared Spectra of all polymers are also done.
