Process for preparing an aqueous suspension, suspension of bis peroxidicarbonate (4-tert-butylcyclohexyl), dimiristyl peroxidicarbonate, uric peracid, or a mixture thereof, and, process of polymerisation

摘要

PROCESS TO PREPARE A AQUAUS SUSPENSION OF BIS PEROXIDICARBONATION (4-TERBUTILCICLE-HEXIL),DIMIRISTIAL PERIODICATION, LAURICO PERMISSION, OR A MISTURE OF THE SAME, AND POLICE PROCESS." a process is provided to produce suspensions of thermally lactic organic compounds. Suspension shall comprise at least one polyvinyl alcohol with an average degree of hydrolysis from 60 to 80% and at least one non-ionic tensoate with an average HBL value of 14,5 to 20,0 and shall be suitable for use in polymerisation processes.a particle size distribution where the d~90~ is smaller than 20 109 . The particle size distribution of the thermologically sluggish organic compound as well as the specific ingredients allows the production of chemical and physically stable suspensions during storage and which combine a high concentration of the compound with low viscosity. When used in the polymerisation processes of vinyl chloride, suspensions ensure a low level of fish eyes and good electrical properties, without adversely affecting the porosity and bulk density of PVC.
