CPVC resin is a novel engineering plastic with wide application prospect, is a novel synthetic polymer material prepared by substitution reaction of polyvinyl chloride (PVC) with specific brands and chlorine under the initiation effect, and is a white or yellowish flowable solid powder. The basic performance is similar to that of PVC, but the CPVC prepared by chloridizing and modifying the PVC resin has obviously improved heat resistance, physical and mechanical properties, chemical stability, flame retardance and the like, and is engineering plastic with excellent quality and low cost. The Vicat softening temperature is increased to 90-125 ℃, the maximum use temperature can reach 110 ℃, and the long-term use temperature is 95 ℃.

The solubility parameters of the CPVC resin and the PMMA resin are very close, the compatibility of the CPVC resin and the PMMA resin is very good, and the CPVC resin and the PMMA resin can be mixed and modified in a relatively high proportion, and the fluidity of the CPVC in the processing process is greatly improved due to the addition of the high-fluidity resin PMMA, and the high shearing caused by the high viscosity of the melt is greatly weakened, so that the good processing performance of the whole formula system is ensured.
However, the power conduit prepared by blending CPVC resin and PMMA resin has the problem of poor toughness, so that the power conduit is easy to damage in the processes of loading, unloading, transporting and laying, and the problems of embrittlement, cracking and the like are more easy to occur particularly in the low-temperature environment.
