摘要：
α-Methylstyrene was polymerized by the anionic living technique, using n-butyllithium as initiator in the solvents, hexamethylene oxide, diethylether, benzene and heptane. 1H NMR was used to determine the stereoregularity of the poly-α-methylstyrene (PMS). Differential scanning calorimetry (DSC) was used to determine Tm, ΔH and ΔS. It was found that the thermal behaviour of PMS depends upon its stereoregularity. © 1990.
