Polycondensation reactions using polymer matrices

No significant effects of molecular weights of P4VP upon those of polymer produced were observed, and suggested that the polycondensation reaction promoted by P4VP may not be a matrix polycondensation in which the molecular weight of the polymer formed can be dependent on the molecular weight of polymer used as matrix. [Pg.10]

Some modifications of the polycondensation in pyridine using triphenyl phosphite in the presence of PEO and P4VP give high molecular weight poly (terephthalamides) as described above. However, the polycondensation reaction with these polymer matrixes do not yield high molecular weight poly(terephthalamides) from p-phenyl-enediamine and 4,4 -diaminodiphenylsulfone with low basicity and poly(m-benz-amide). [Pg.16]
