本文根据Anderson-Beyer-Watson基团法,采用数据库技术,用微机计算聚合反应的焓与熵变。该法简便易行,对常见乙烯基单体聚合焓与熵的估算结果与文献值十分接近。并用热力学讨论了苯乙烯自由基聚合对歧化或结合终止的选择性。
In this paper, according to the Anderson-Beyer-Watson group method, the database technology was used to calculate the enthalpy and entropy change of the polymerization reaction by computer. The method is simple and easy to calculate. The calculation results of the enthalpy and entropy of the common vinyl monomer are very close to the literature values. The selectivity of styrene radical polymerization to disproportionation or binding termination was also discussed by thermodynamics.
