FIBERS FORMED OF ESTER CONDENSATES AND PROCESS FOR FORMING FIBERS FROM ESTER CONDENSATES

摘要

Fibers are formed from ester condensates of polyhydric alcohols and organic polyacids or anhydrides. The process for making the fibers comprises forming a reactive mixture from a polyhydric alcohol and organic polyacid mixture heated to produce a low molecular weight ester condensation product which is subsequently pumped through a spinneret causing additional ester condensation reaction in situ with fiber formation.
