USE OF RADICALS 2,2,6,6 TETRAALQUILPIPERIDINA-N-OXILO WITH LONG RENT CHAINS AS POLYMERIZATION REGULATORS.

摘要

A process for the preparation of an oligomer, a cooligomer, a polymer or a copolymer (block or random) by free radical polymerization of at least one ethylenically unsaturated monomer or oligomer, the process of which comprises heating the monomer or monomers / oligomers in presence of a source of free radicals and a compound of formula I, and polymerization of the ethylenically unsaturated monomer or oligomer in a polymer with a polydispersion of 1.1 to 2.2 and, in which the compound of ** formula ** .
