Abstract
The present invention relates to a method of preparing a heat-resistant resin, a heat-resistant resin, and a heat-resistant ABS resin. According to the preparation method of the present invention, the heat-resistant resin can be prepared at a high polymerization conversion rate within a shortened polymerization time, and the amount of polymerized coagulum and the content of fine particles upon coagulation are decreased. Accordingly, a heat-resistant resin and a heat-resistant ABS resin composition with enhanced heat deflection temperature and processability are provided.
