Abstract
A non-coagulative organosilicone resin is produced by causing an organosilicon compound containing an isocyanate group and possessing a siloxane-forming property to react with heparin in order to produce an organosilicon compound having a heparin residue linked thereto and subsequently causing the resultant organosilicon compound to react with an organosilicone resin intermediate capable of undergoing a polycondensation reaction via silanol intermediates and consequently forming a siloxane cross-link.
