| titleOfInvention | Method for producing amorphous heat-resistant resin having ring structure in main chain |
| abstract | A method for producing an amorphous heat-resistant resin having a ring structure in the main chain, which can provide an amorphous heat-resistant resin having excellent transparency and heat resistance, and a catalyst used for forming the ring structure The present invention provides a production method that can suppress foaming that occurs when the obtained resin is molded without a deactivation treatment. A polymer having a carboxyl group or a hydroxyl group and an ester group in a molecular chain, which is a precursor of an amorphous heat-resistant resin having a ring structure in the main chain, between the carboxyl group or the hydroxyl group and the ester group. A method for producing the resin by forming the ring structure in the main chain of the polymer by advancing a dealcoholization cyclocondensation reaction, wherein the catalyst used for the progress of the reaction is a compound of a group 12 element There is a method.
