摘要

以二(7-辛烯基)二甲基硅烷(含柔性间隔基二甲基硅烷的非共轭

-二烯)为交联剂，将同步交联烯烃聚合(SCOP)技术引

入丙烯多相共聚体系，通过连续改变其浓度制备颗粒形态可控的高橡胶含量(60 wt%)聚丙烯热塑性弹性体(R-TPO)，并系统考察了交联剂浓度与链拓扑结构及颗粒相形态之间的内在关联. 结果表明，与常规非共轭

-二烯(如1

9-癸二烯)相比，Si―C键赋予的旋转自由度使二(7-辛烯基)二甲基硅烷交联剂在丙烯多相共聚中的长链支化效率获得显著提升，长链支化临界浓度(

Abstract

To address the particle agglomeration caused by ethylene-propylene rubber (EPR) phase migration in the industrial production of high-rubber-content thermoplastic polyolefin (TPO) elastomers

as well as the bottleneck of low long-chain branching (LCB) efficiency associated with 1

9-decadiene (DD)

this study proposes a conformational flexibility mod

ulation strategy based on our previously established tri-concentration theoretical framework (

critical

induction

gel

) for simultaneous crosslinking olefin polymerization (SCOP). A novel non-conjugated

-diene monomer featuring a flexible ―Si(CH

)

― spacer

bis(7-octenyl)dimethylsilane (D8M2)

was designed and synthesized. Leveraging the low rotational energy barrier and elongated bond length of Si―C bonds

steric hindrance was significantly mitigated

boosting the LCB efficiency from 8% (for DD) to 94.2%. The effects of D8M2 concentration on polymerization kinetics

molecular chain topology

and phase morphology were systematically investigated

validating the universality of the SCOP theoretical framework for silicon-functionalized monomers. Mechanistic studies revealed that the conformational entropy advantage of the ―Si(CH

)

― group accelerated molecular chain relaxation while promoting efficient crosslinking

creating an intrinsic trade-off between high insertion efficiency and weak topological constraints. Consequently

a relatively high concentration (0.075 mol/L) is required to achieve a non-agglomerated particle dispersion. This study elucidates the quantitative structure-property relationship between conformational flexibility and topological constraint strength

providing crucial theoretical guidance for the molecular design of SCOP technology.
