In order to develop novel rubber materials with satisfied integrated properties and utilize the advantagies of trans-1,4-polydienes like trans -1,4-polyisoprene (TPI) and trans butadiene-isoprene copolymer (TBIR), such as strain induced crystallization, excellent anit-fatigue properties, low abrasion loss, low rolling resistance, etc., the applicants design and synthesize novel TPI/TBIR alloys with reactor granules technology for the first time by using bulk polymerization method and sphercial TPI/TBIR rubber alloys with multi-phase and multi-component are synthesized within reactor. This is a novel, green and energy saving polymerization technology in rubber synthesis field. This project will resolve the following key scientific problems: ①control methods for the alloy paritcle morphology within reactor, ② fractionation methods for the trans rubber alloys,③study the copolymer content, fractions, comonomer content and sequence distribution, ④study the phase structure and the crystallization behavior of the rubbe alloys，grasp the relationship between the properties and the aggregation structures of the rubbe alloys, ⑤ study the polymerization mechanism of the supported Ziegler-Natta catalyst for diene polymerizaiton and the controllable method for the catalytic behavior. We hope that we can provide a new kind rubber stock for high performance tires in tread and side wall, as well as a novel synthetic polymerization technology for rubber synthesis.
