POLY(P-VINYLTRIFLUOROACETOPHENONE) - NEW CRYSTALLINE POLYMER PREPARED BY RADICAL INITIATION

Results of an experimental investigation are presented in which the above crystalline polymer has been synthesized in solution of benzene with asobisisobutyronitrile as the initiator. The monomer has been prepared from vinylphenylmagnesium chloride and trifluoroacetic acid. Crystallinity of polymers obtained was determined by x-ray diffraction. Some physical properties were determined by DTA. It is demonstrated that the unusual crystallinity of PVTFA is due to the unique size and interactions of the trifluoroacetyl moiety on the polymer side chains, although the details as to how the trifluoroacetophenyl groups interact and arrange in space are still not clear.
