Abstract

L'invention concerne les industries biochimiques. Elle a pour objet un polyuréthanne auquel est unie une protéine en conséquence de la réaction de celle-ci avec un polyuréthanne prépolymère liquide à radicaux isocyanate terminaux qui est soluble ou dispersable dans l'eau. La solution est dispersée ensuite dans l'eau. Cette protéine est préférée comme réactif à longue durée de conservation pour des réactions biologiques.
