Zwitterionic polymerization catalyst

摘要

The present invention is a new catalyst compositions and methods of making and using the same. These compositions comprise organometallic salts with large noncoordinating anions which contain at least one terminal unsaturation and the high dipole moment Zwitterions that these can isomerize into. During polymerization, the ionic pairs are dispersed within the polymer particles. The length of space separating the positive and negative end of the Zwitterion also increase as a consequence of polymerization. Additionally, polymerization proceeds without the need of a co-catalyst.
