Abstract
The invention relates to a process for preparing a branched polymer by contacting a monofunctional or difunctional polymer whose functional group is at least an —OH or an —NH2 group with a multifunctional compound RYn, where n>2 and Y is an —OH group, an —NHm group where m=1,2 or a —COOH group and R is an alkyl, an aryl group or a cyclic group and in which the Y groups need not be the same and in which carbonyl bislactamate is also present.
