METHOD OF PREPARING VINYLCHLORIDE-BASED RESIN CAPABLE OF PRODUCING PLASTISOL WITH LOW VISCOSITY, VINYLCHLORIDE-BASED RESIN PREPARED USING THE METHOD, METHOD OF PREPARING VINYLCHLORIDE-BASED PLASTISOL, AND VINYLCHLORIDE-BASED PLASTISOL PREPARED USING THE METHOD

摘要

Provided is a method of preparing a vinylchloride-based resin. The method includes adding to a vinylchloride-based latex an acid, preferably, 1-7 parts by weight of the acid based on 100 parts by weight of a solid of the vinylchloride-based latex; optionally, incubating the resultant mixture at a temperature of 30~60° C. for 30 minutes to 3 hours; and drying the mixture. Therefore, it is possible to reduce the viscosity of a vinylchloride-based plastisol, thereby improving the processability of the plastisol.
