Determination of rate constant of primary intra-crosslinking reaction in crosslinking copolymerization

Based on the property of intrinsic viscosity of intra-crosslinking polymer, a new method to determine the rate constant of the primary intra-crosslinking reaction was developed in the crosslinking copolymerization. Furthermore, the method was testified in the copolymerization system of vinyl chloride/diallyl phathalate.
