Stereoregular trans ‐arylene‐silylene‐vinylene polymers of M w =13100–34800 and PDI=1.6–2.9 of the general formulas CH 2 CH[SiMe 2 C 6 H 4 ‐SiMe 2 CHCH]( 16, 17, 18 ) and CH 2 CH[(R)CHCHC 6 H 4 CHCH](where R=Me 2 Si‐ p C 6 H 4 ‐ SiMe 2 , Me 2 Si‐ m C 6 H 4 SiMe 2 and Me 2 SiC 6 H 4 C 6 H 4 SiMe 2 ) ( 19, 20, 21 ) have been effectively synthesized via silylative coupling (SC) homopolycondensation of bis(vinyldimethylsilyl)arenes ( 10, 12, 14 ) and cross‐polycondensation of 4‐(vinyldimethylsilyl)styrene ( 11 ) as well as cross‐copolycondensation of bis(vinyldimethylsilyl)arenes ( 10, 12 and 14 ) with 1,4‐divinylbenzene ( 9 ) catalyzed by [RuH(Cl)(CO)(PCy 3 ) 2 ] ( 7 ). Such highly stereoregular products cannot be synthesized via ADMET polycondensation or ring opening metathesis ROM or polyaddition of hydridosilanes to acetylenes.
