4,4’-Isopropylidene bisphenol

The high-molecular block-copolyarylenesterketones have been S5m-thesized on the basis of 4,4 -difluorobenzophenone and number of bisphe-nols by means of reaction of nucleophylic substitution of activated aryl-halogenide in dimethylacetamide (in the presence of potassium carbonate) [394, 395]. It has been identified the cutback of molecular weight of polymer when using bisphenolate of 4,4 -(isopropylidene)bisphenol. [Pg.166]

The most important polycarbonate in commercial terms is derived from 4,4 -isopropylidene-bisphenol. The photodegradation behaviour of this material has been extensively studied both in the absence and presence of air. ... [Pg.1298]
