Process for preparing resorbable polyesters by bulk polymerization

A process for preparing resorbable polyesters by bulk polymerization, comprising:

• melting and homogenizing reaction components in a reactor to form a reaction mixture;
• transferring the reaction mixture into a polymerization reactor, the polymerization reactor comprising:
• a plurality of reactor walls including at least two fittings configured to releasably connect adjacent reactor walls of the plurality of reactor walls, and
• a plurality of connected lumens formed by the connected adjacent walls,
• wherein a shortest distance of any point within a single lumen of the plurality of connected lumens to an adjacent reactor wall is less than 8 cm;
• polymerizing the reaction mixture at a temperature between about 50° C. and 230° C. to form a resorbable polyester;
• and
• removing the resorbable polyester from the polymerization reactor by disconnecting the at least two fittings of the plurality of reactor walls to expose the resorbable polyester lengthwise.
