The second phase, which led to the actual polymer at 200–240°C, required the catalytic action of SnC 2 O 4, Sb 2 O 4, Sb 2 O 3 and Ti(OBu) 4. Specific problems, related to some fragile moieties, limited the success of these polymerizations to a number of combinations that gave polyesters bearing regular structures and molecular weights of up ...
