摘要：

The anionic polymerization of N,N,N',N'-tetraethyl-4-isopropenylphenylphosphonous diamide (PA) was studied. From the kinetic analyses, the thermodynamic parameters, DELTA-H(ss) and DELTA-H(ss), and the ceiling temperature, T(c), of the polymerization reaction of the PA monomer were found to be -6.5(1) kcal mol-1, -2.3(0) x 10 cal mol-1 K-1, and 283 K, respectively. It is concluded that if the polymerization of the monomer is initiated with n-butyllithium in tetrahydrofuran above its T(c) and then propagated below T(c), the polymerization proceeds at a first-order reaction rate without side reactions. The resulting poly(PA)s have predictable molecular weights and narrow molecular weight distributions.
