  • Method for producing a TEMPOL-containing urethane resin composition having an improved storage stability
    Patent number: 11124598
    Abstract: A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.
    Type: Grant
