Reliability and Performance of Vinyl LactamBased Kinetic ...However, this could improve the KHI performance if the molecular weight range is reduced to shorter, but not too short, polymer chains. Thus, ballmilling or some other kind of mechanical strain degradation might be a way to produce shorter and more optimal KHI polymers from larger polymer chains if they were not easily available by other means.
