Abstract
The present invention relates to a latex containing two populations of particles of polymers based on vinyl chloride, respectively exhibiting mean diameters of between 0.9 and 1.3 .mu.m and between 0.15 and 0.3 .mu.m, in proportions such that the ratio by weight of the population with the lesser mean diameter to that with the greater mean diameter is between 0.4 and 0.7. Other subjects of the present invention are processes for the manufacture of the said latex and its application in fluid plastisols and foams of very good cellular quality.
