Abstract

N-Phenylmaleimide (N-PMI) was polymerized by 9-borabicyclo[3.3.1]nonane (9-BBN) in tetrahydrofuran under argon at 0 degrees C. The molecular weight distributions of the resulting polyers were around 1.1. The rate of polymerization was proportional to [9-BBN](1.18) and [N-PMI](1.24). Hydroquinone had little effect on the rate of polymerization and on the molecular weight of the polymers obtained. Triethylamine completely inhibited the polymerization, and aniline with a relatively smallpK(a) value and zinc iodide effectively retarded the polymerization. The polymerization did not proceed either in polar dimethylformamide or in non-polar toluene. In polymerizations at temperatures higher than60 degrees C the conversions decreased. On the basis of the results, a non-radical mechanism was proposed for this polymerization.
