METHOD OF INTRODUCING CARBONYL GROUPS INTO POLYMERS Russian patent published in 2004 - IPC

Abstract RU 2230754 C1

FIELD: polymer production.

SUBSTANCE: modified polymers are prepared by nitrogen monoxide-mediated oxidation of initial polymers containing double carbon-carbon bonds until oxygen level in polymer attains 3-40 wt %. As a result, polymers carrying carbonyl groups are obtained. Method allows introduction of carbonyl groups with no other additional groups and without formation of by-products such as catalyst residues, etc.

EFFECT: avoided necessity of purifying polymer and performing complex treatment of modifying agent degradation product.
