Al. Rusanov et al., SYNTHESIS AND INVESTIGATION OF AROMATIC P OLYETHERS BEARING ACETYLENIC GROUPS IN BACKBONES, Vysokomolekularnye soedinenia. Seria A, 40(3), 1998, pp. 397-402
New aromatic difluoroaromatic compounds containing acetylenic groups w
ere obtained. Reactions of these monomers with various bisphenols unde
r the conditions of nucleophilic substitution yielded aromatic polyeth
ers. The glass transition temperature of the resulting polymers lies i
n the range of 145-280 degrees C, and the temperature of 10% weight lo
ss measured upon heating in air lies in the range of 410-530 degrees C
. These polymers produce cross-linked structures at elevated temperatu
res.
