摘要: 本文采用旋转异构态模型,考虑排斥体积效应,用 Monte Carlo模拟方法计算了聚亚甲基高分子链的温度系数dln
/dT。考虑排斥体积的聚亚甲基链的温度系数大于无扰聚亚甲基链的温度系数,并更接近实验值。 Abstract: In this paper, we calculate the temperature coefficients. dln_0/dT ofpolymethylene chains with excluded volume using Monte Carlo simulation and therotational--isomeric state (RIS) model. We find that the temperature coefficient ofpolymthylene chains
