What is Aromatic polymers obtained by precipitation polycondensation: 5 * *Part 4: Zolotukhin, M.G., Rueda, D.R., Balta Calleja, F.J., Cagiao, M.E., Bruix, M. and Gileva, N.G. Polymer, 1997, 38, 1471 . 1 H and 13 C n.m.r. study of poly(ether ketone ketone)s about?

Highmolecular weight, lineararomaticpoly(ether ketoneketone)swithdifferent iso-/tere-isomer repeating unit ratio (100/0, 50/50,0/100)havebeenstudiedby 1H and 13Cn.m.r.spectroscopy. Thepolymerswere obtainedin particleformbyprecipitationelectrophilic Friedel-Crafts acylationcondensation of iso-and terephthaloyl chlorides withdiphenyl ether,1,4-and l,3-bis(4-phenoxybenzoyl)benzenes. Conventional IH and 13Cn.m.r. spectroscoy showspara-substitution in the diphenyl etherfragmentsof the mainchain. ? Analysisoftheexpanded H n.m.r.spectrafor theringprotonresonances revealsdefectmeta-and orthostructures.Theamountand isomerratio of thesedefectstructuresdependon the polymerstructureand preparationpath. Thelowfieldof IH n.m.r.spectraofpolyketones basedon 'small monomers' (diphenyl etherand iso-and terephthaloyl chlorides) werefoundto showadditional minorsignalscorresponding to a differenttype of defectstructure.A possiblemechanismof formationof these defectstructuresis discussed. @ 1997ElsevierScienceLtd.
