Abstract
The present invention relates to novel isocyano derivatives of linear or cross-linked, natural or synthetic macromolecules, the derivatives being of the general formula P--O--Q--NC, wherein P is the macromolecular backbone, the oxygen atom is part of the hydroxy group, Q is a group --(CH.sub.2).sub.n --wherein n is an integer of at least 3 carbon atoms, and up to about 20 carbon atoms, or Q is an aralkyl group, to a process for preparing such derivatives and to a process of linking to same biologically active proteins and to the products thus obtained.
