这篇英文是关于PVC耐热改性的.
Conclusion
The recurrence method is suitable for predicting
the variations of instantaneous and integral copoly-
mer compositions with conversion for both copoly-
merization and terpolymerization systems. Copolymer
composition varied greatly with conversion for VC/
PMI copolymerization system. The ranges of mono-
mer feed fraction with the integral copolymer compo-
sition error lower than 0.05 or 0.1 for VC/PMI
copolymerization system are very small. The addition
of a third monomer (such as AN or MMA) could
improve the condition. It is revealed that it is more
suitable to take the integral terpolymer composition
of PMI as the control parameter for VC/PMI/AN
and VC/PMI/MMA suspension terpolymerization sys-
tems from the viewpoints of heat resistance and econ-
omics. The optimum regions of monomer feed
fractions suitable for the two terpolymerizations are
obtained. By utilizing
