POLYVINYL CHLORIDE RESINS OF THE CONVERTED PLASTISOL TYPE, HAVING IMPROVED ABILITY TO PLASTIC ABSORPTION, AND METHOD FOR OBTAINING SUCH IMPROVEMENT

摘要

P THIS PROCESS FOR THE TREATMENT OF POLYVINYL CHLORIDE RESINS OF THE PLASTISOL TYPE HAVING A LOW GRANULOMETRY AND A RELATIVE LOW ABSORBENCY IN PLASTICIZERS. IN ACCORDANCE WITH THIS PROCEDURE, THE RESIN IS HEATED AND THE ABILITY TO ABSORB PLASTICIZERS IN A FLUID MEDIUM AT A TEMPERATURE NOT LESS THAN 66C WILL BE IMPROVED. PREFERABLY, THE FLUID MEDIUM IS A LIQUID MEDIUM, AND PARTICULARLY WATER. /P
