Method for introducing carbonyl groups into polymers containing double carbon-carbon linkages |
摘要 |
The invention discloses a method for selectively introducing carbonyl groups into polymers by oxygenation of double C-C bonds of polymers with the aid of nitrous oxide (N<SUB>2</SUB>O) at a temperature comprised between 50 and 350° C. and a pressure of N<SUB>2</SUB>O of from 0.01 to 100 atmospheres. The introduction of an insignificant amount of C-O groups allows one to modify the physico-chemical properties of a polymer, with its molecular weight and molecular-weight distribution preserved. Deeper oxygenation results in controlled cleavage of polymer macromolecules and makes it possible to produce oxygen-containing oligomers having a desired molecular weight. |
