苯乙烯-丙烯酸丁酯分散共聚合动力学
关键字：dispersion polymerization, poly(St-BA), kinetic of polymerization
分散聚合法是一种制备微米级单分散聚合物微球的简单而易行的方法。目前，对于分散聚合的研究主要集中在微球的粒径分布上，如苯乙烯[3]等单体的均聚，及苯乙烯与甲基丙烯酸甲酯[4]单体的分散共聚合，对分散聚合动力学的研究较少。

[Macromol. Chem. Phys.] Thermoresponsive Poly(2-oxazoline) Molecular Brushes by Living Ionic Polymerization: Kinetic Investigations of Pendant ChainGrafting and Cloud Point Modulation by Backbone and Side Chain Length Variation
Molecular brushes of poly(2-oxazoline)s were prepared by living anionic polymerization of 2-iso-propenyl-2-oxazoline to form the backbone and subsequent living cationic ring-opening polymerization of 2- n - or 2- iso -propyl-2-oxazoline for pendant chain grafting. In situ kinetic studies indicate that the initiation effi ciency and polymerization rates are independent from the number of initiato...

31. Isothermal and nonisothermal melt crystallization kinetic behavior of poly(aryl ether biphenyl ether ketone ketone): PEDEKK. Liu TX, Mo ZS, Zhang HF. J. POLYM. ENG. 18 (4): 283-299 1998.
Isothermal and nonisothermal melt crystallization kinetics of a novel poly(aryl ether ketone), PEDEKK, were investigated by differential scanning calorimetry. Several kinetic analyses were used to describe the crystallization behavior. The activation energies were determined as 425 and 176 KJ/mol for isothermal and nonisothermal crystallization, respectively. The equilibrium melting point T-m(o) w...
