Polyformals aromatic containing

Polyformals containing secondary allylic and benzylic groups undergo complete acidolytic decomposition to volatile products such as an aromatic com-... [Pg.145]

Preliminary information on new aromatic polyformals based on other bisphenols is contained in Table 7. Most of these materials have been made only once and no extensive characterization of the polymers has been made. None of these polyformals were examined for cyclic oligomers. Where possible, the T for the corresponding polycarbonate is also given. All polymerizations were run in NMP/ CH9CI9 mixtures except when the bisphenol contained an electron 0... [Pg.79]

Telechelic aromatic-aliphatic polyformals containing only primary alcohol chain ends can be conveniently synthesized from a bisphenol and an a,ft>-bis(chloromethoxy)alkane in the presence of a phase transfer catalyst as outlined in Scheme 66. This is in spite of some competing side reactions that are discussed elsewhere. ... [Pg.1116]
