PRODUCTION PROCESS AND USE FOR TRANSPARENT HEAT-RESISTANT RESIN

摘要

PURPOSE: A production process for a transparent heat-resistant resin, and further, a transparent heat-resistant resin and uses therefor are provided, wherein the production process involves high dealcoholation conversion and a low content of residual volatiles in the resultant resin. CONSTITUTION: A production process for a transparent heat-resistant resin comprises the step of running a dealcoholation reaction of a polymer having a hydroxyl group and an ester group in its molecular chain to introduce a lactone ring structure into the polymer to obtain a transparent resin having the heat resistance, and is characterized in that the dealcoholation reaction is run in the presence of a solvent, and further characterized by further comprising a devolatilization step which is carried out jointly with the dealcoholation reaction.
