Production of aromatic amorphous thermoplastic polymers.

摘要

The method of preparing a thermoplastic polyarylether polymer which comprises reacting a first monomer composition comprising an activated dihalobenzenoid compound and a dihydroxydiphenyl aliphatic monomer in a molar ratio of dihalobenzenoid compound to dihydroxybenzenoid compound of at least 1.2 to 1, adding to the product a second monomer composition comprising a dihydroxybenzenoid compound comprising at least one compound which is free of aliphatic moieties and polymerizing.
