<p>Process for the polymerization, in an aqueous suspending medium, of vinylidene fluoride with the aid of an oil-soluble free radical polymerization initiator in the presence of a suspending agent and a chain regulator chosen from the bis(alkyl) carbonates, the alkyl groupings of which contain not more that five carbon atoms wherein the molecular weight of vinylidene fluoride polymers are effectively regulated without having a detrimental effect on the polymerization yield, thus the vinylidene fluoride polymers have a good stability to heat.</p> |
