ABSTRACT:
A method of modifying polymers comprises contacting a selected normally non-reactive polymer with a catalyst in an inert atmosphere in a contacting zone. The catalyst comprises a metal carbonyl of a group VIII transition element, the contacting being effected for a time sufficient to change the characteristics of the polymer. Preferably, the carbonyl is selected from the group consisting of iron carbonyl, nickel carbonyl, cobalt carbonyl and mixtures thereof and most preferably iron pentacarbonyl is employed. The polymer contains saturated carbon chains having carboxylic groups. Novel modified polymer products are recovered.
