TWO-POPULATION VINYL CHLORIDE POLYMER LATEX HAVING A HIGH POPULATION RATE OF FINE PARTICLES, PROCESS FOR ITS PREPARATION AND ITS APPLICATIONS

摘要

the present invention relates to a latex containing two populations ofparticles of vinyl chloride based polymers having respectively.mean diameters of between 0.9 and 1.3 mm and 0.3 mm and 0.15 insuch proportions that the weight ratio of the population diameteron the average diameter is between 0.4 and higher0.7. it also aims, methods of manufacture and application of latex foam fluid plastisols and of very good qualitycell phone.
