Notes:
Crystallization of polyterephthalates of bis(4-hydroxy-3-chlorophenyl)-2,2-propane synthesized by an acceptor-catalytic polyesterification has been investigated quantitatively. It was found that in a homogeneous medium (in solvents for the polymer) amorphous polymers are formed, while polycondensation in a heterogeneous system (in nonsolvents for the polymer) gives rise to crystalline polyarylates, their degree of crystallization being dependent on synthesis conditions. Secondary treatment of resulting polymers can result in their crystallization and amorphization. Along with molecular weight the physicomechanical properties are significantly affected by the preparation method.
