PROCESS FOR THE CONTROLEED RADICAL POLYMERIZATION OR COPOLYMERIZATION OF (METH)ACRYLIC, VINYL, VINYLIDENE AND DIENE MONOMERS, AND (CO)POLYMERS OBTAINED

摘要

The present invention is the polymerization or copolymerization of one or more monomers in bulk, solution, emulsification or suspension at temperatures as low as 0 ° C. in the presence of at least one metal complex catalyst of the formula MA _a (L) _n and at least one radical-generator compound. (M = Cu, Ag or Au; A = halogen, pseudohalogen or carboxylate group; L = ligand of M selected from the following formula); (Y = N or P);;R ¹ , R ² , R ³ , R ⁴ , R ⁵ and R ⁶ = hydrogen atom, C ₁ -C ₁₀ alkyl group, aromatic group or heteroaromatic group; Z ¹ , Z ² and Z ³ = one of the following formulas:;(R ⁷ -R ¹⁹ = hydrogen atom, C ₁ -C ₁₀ alkyl group, aromatic group or heteroaromatic group; R ¹⁹ and R ²⁰ = hydrogen atom, halogen atom, C ₁ -C ₁₀ alkyl, C ₁ -C ₁₀ alkoxy or -(CR ²¹ R ²² ) _r NR ²³ R ²⁴ , wherein R ²¹ , R ²² , R ²³ and R ²⁴ = hydrogen atom, C ₁ -C ₁₀ alkyl group, aromatic group or heteroaromatic group, r = 1-10 An integer; and at least ^{two of} Z ¹ , Z ² and Z ³ are each hydrogen atom; o, p and q are integers of 1-10, and the linked residues Z ¹ , Z ² or Z ³ are each -NR ¹⁹ R ²⁰ 0 except where indicated; a = 1 or 2; n = 1, 2 or 3.)
