Received Date: 18 May 1991

The copotymerizations of p-diethynyibenzene(PDEB)with phenytacetylene(PHA), 4, 4'-diethynytbiphenyt(DEBP)or m-diethynylbenzene(MDEB)are studied in various mole ratios of monomers.The sotubitity parameter(σ_p), swellabitity(θ_p), Huggins parameter(X), density (d₄²⁵)and the average motecutar weights between crosstinks (M_c) of obtained copotymers are measured.The IR spectra of these copolymers are recorded.The mechanism about the polymerization of acetytenic derivatives initiated by(Ph₃P)₂PdCl₂ is discussed.
