摘要
New isocyanate (NCO) prepolymers (I) are obtained by reacting (a) organic isocyanates with (b) components containing H-acid compounds at 20-90 deg C, in which component (b) is a mixture of (b1) difunctional alcohol(s), (b2) trifunctional alcohol(s), (b3) stabilizer(s) and optionally (b4) polyols and reaction of (a) and (b) is carried out in vinyl monomer(s). An Independent claim is also included for the preparation of prepolymers (I) in this way.
