PROCESS FOR THE PREPARATION OF FUNCTIONAL LACTON POLYMERS, POLYLACTONES AS ALSO OBTAINED, AND THEIR USE. |
| abstract |
Process for the preparation of a lactone polymer functionalized at the chain ends, comprising reacting the lactone with a polymerization initiator of the formula: alk dp- M - (- oR (y) n-Xm -) - p in which the symbols have different meanings, in the presence of an organic solvent so as to obtain an intermediate compound by opening the cycle repeatedly at the acyl-oxygen bond of the lactone, and either the acid hydrolysis of the resulting intermediate compound for obtaining the corresponding functionalized lactone polymer, either coupling the resulting intermediate compound to obtain the functionalized lactone polymer of doubled molecular weight, or reacting the resulting intermediate compound with a functional reagent to obtain the corresponding functionalized lactone polymer. |
