<p>In the process according to the invention for the aqueous suspension polymerization of vinyl chloride, alone or as a mixture with another vinyl monomer, the polymerization initiator comprises at least one compound chosen from dialkyl peroxydicarbonates, peroxy-tert-alkanoates and diacyl peroxides and use is made, as agent for halting the polymerization, of a mono- or disubstituted hydroxylamine. The resins thus obtained exhibit improved color and heat stability.</p> |
