Strålningshärdbar dendritisk oligomer eller polymer

摘要

A radiation curable dendritic oligomer or polymer obtainable by addition of at least one secondary amine to at least one acrylic double bond in a dendritic acrylate oligomer or polymer is disclosed. Said radiation curable oligomer or polymer nominally has at least one acrylic double bond and at least one tertiary amine group. In a further aspect, the present invdention refers to a process for production of said radiation curable dendritic oligomer or polymer. Said process comprises the step of acrylation of a dendritic polymer nominally having at least two terminal hydroxyl groups and the step of Michael addition of at least one secondary amine to at least one acrylic double bond. In yet a further aspect, a radiation curable composition comprising said dendritic oligomer or polymer is disclosed.
