Luxuriant metals catalyst and tradition B C rubber catalyst of comparison

Luxuriant metals catalyst from the transition metalses, such as Gao, Jia and titanium...etc. and wreath E two wreath forms such as Xi(Wu wreath, Mao wreath) and its derivatives etc. not saturation structure lord catalyst and the A Ji aluminum oxygen alkane(MAO) help catalyst to constitute.

The tradition B C rubber produce first adoption the Fan fasten catalyst system, existence activity low, the life span be short, toxicity Gao and polymer color deep etc. weakness, have already been eliminate.B C rubber equip application currently more is a titanium to fasten catalyst system, its activity Gao but easy born ethylene long chain segment, creation crystallize, influence rubber function.But the luxuriant metals catalyst have tradition Fan to fasten, the titanium fasten the incomparable advantage of the catalyst:(1)Come together an activity Gao;(2)The opposite member quality of outcome distribute narrow;(3)Total gather a list a body to combine even;(4)Can carry on a rules to come together;(5)I am strong to the adaptability of the existing craft to lead.Because the luxuriant metals catalyst come together activity Gao, the catalyst dosage be little, the remaining thing content be little, so come together an outcome need not take off in addition to remaining catalyst, the product color be deeply bright, the polymer structure be even, the opposite member quality of outcome distribute narrow, physics the machine function be excellent and particularly pass change luxuriant metals structure

Can accurately regulate ethylene, C Xi with two constitute of alkenes, adjust tiny view structure of control the polymer in the very big scope, synthesize to submit to have new chain structure thus of, dissimilarity the product of the use.Activity one, efficiently luxuriant metals catalyst development success doubtless give B C rubber industry of development infusion new of motive.

The luxuriant metals catalyst usually can is divided into a common type, bridge chain a type with limit several He2 Gou4 Xing2's etc. be a few structure.Currently after B C rubber apply realm already industrialize of have another is both.It the concrete contents of various structure BE:(1)Common structure type, this is at the earliest stage usage of a kind of luxuriant metals catalyst, structure more simple, is 2 wreath E two Xis clip to hold a transition metals of alkyl compound or Lu turn a thing, among them double wreath E two Xi can drive double Mao Ji or double Wu Ji replace;(2)The bridge chain structure type, it is at common structure type foundation top use alkyl conjunction 2 wreath structure, in order to prevent the structure revolve and give luxuriant metals catalyst corpus rigid;(3)Limit several He2 Gou4 Xing2, it is replace with the ammonia Ji common structure in of a wreath E be two Xi Jis and make a bridge chain by the alkyl or the Huo alkyl and another wreath E two Xi Jis connect and synthesize B C rubber with it can design and control polymer member structure, much dispersion with long chain turn structure and list the body combine quantity.
