Abstract
The synthesis of poly(3,3-phthalidylidene-4,4'-biphenylylene) (PPB) by precipitative Friedel-Crafts homopolycondensation of 3-(4-biphenylyl) -3-chlorophthalide was studied. The polymer-catalyst complex precipita ted from the initially homogeneous reaction mixture was shown to be ac tive and providing the growth of macromolecular chains. The polymer ob tained in the form of smooth, transparent grass-like particles, depend ing on the reaction parameters, may have either uni- or bimodal molecu lar weight distribution. Molecular characteristics were not found to d epend on the size of the polymer particles. ''Precipitative'' PPB show s improved properties and higher crystallinity in comparison with ''so lution'' PPB.
