摘要： WHEREIN R IS A SATURATED OR UNSATURATED HYDROCARBON RESIDUE HAVING 13 TO 19 CARBON ATOMS, OR 1 TO 5% BY WEIGHT OF THE SAID MONOGLYCERIDE AND 0.01 TO 5% BY WEIGHT OF A PLASTICIZER, BASED ON THE SAID MONOMER OR THE MIXTURE THEREOF. THE VINYL CHLORIDE RESIN THUS OBTAINED IS EXCELLENT IN PROCESSABILITY AND THERMAL STABILITY.

HO-CH2-CH(-OH)-CH2-OOC-R

AN ANTISATIC VINYL CHLORIDE RESIN IS PRODUCED BY SUBJECTING VINYL CHLORIDE, OR A MIXTURE THEREOF WITH A MINOR AMOUNT OF ETHYLENICALLY UNSATURATED MONOMERS COPOLYMERIZABLE THEREWITH, TO AN AQUEOUS SUSPENSION POLYMERIZATION IN THE PRESENCE OF 1 TO 5% BY WEIGHT, BASED ON THE WEIGHT OF SAID MONOMER OR THE MIXTURE THEREOF, OF A MONOGLYCERIDE REPRESENTED BY THE GENERAL FORMULA,
