Disclosed herein are polyalphaolefins and Salan cataylsts, catalyst systems, and processes to produce the polyalphaolefins. The salan catalysts of the invention are applied as unitary compounds with the activators built in the conjugate ring structure, wrapping around a Group IV metal. The method allows production of highly steroregular products with narrow distribution of molecular masses of the growing polymer chains.
本文披露了聚α烯烃和Salan催化剂,催化系统以及生产聚α烯烃的过程。该发明的Salan催化剂作为具有活化剂的单一化合物应用于共轭环结构中,包裹在第四族金属周围。该方法允许生产高度立体规整的产物,具有生长聚合物链的分子质量狭窄分布。
