摘要/Abstract

摘要： 本文研究了α-甲基苯乙烯聚合热力学。发现平衡单体浓度不仅与聚合温度有关,而且依赖于引发剂浓度。本文还报导了缔合体和单量体引发β-甲基苯乙烯聚合的平衡常数、聚合热、浆合熵及聚合自由焓。

Abstract: The thermodynamics of equilibrium polymerization of alpha-mclhylslyrene had been investigated. It was observed that the equilibrium monomer concentration[M]_e is dependent not only on the temperature but also on the initiator concentration [BuLi]_o.This phenomenon could be easily elucidated by the mechanism of polymerization proposed, and the mathematic relationship batween [M]_e and [BuLi]_o was obtained.Furthermore, the equilibrium constants of anionic equilibrium polymerization K₁, K₂, the free-energies ΔG₁, ΔG₂, heats of polymerization ΔH₁, ΔH₂,and entropies of polymerization ΔS₁, ΔS₂, of monomenc and associated reactive species were reported.
