“…Our results do not shed sufficient light on the above mechanisms to permit conclusions. Chlorine abstraction, as shown in mechanism (1) was reported to occur in one case of grafting on a polyvinyl chloride backbone.1° In our work, chlorine analyses on the products of grafting indicated that the chlorine content was within experimental error of the amounts calculated for molecular structures resulting only through hydrogen abstraction. Specifically, if Polymer I formed through proton abstraction alone, it should contain 50.93% chlorine.…”

“…The three types of polymers used as backbones for grafting were (1) backbone #1, homopolymers of vinyl chloride, 9 = 0.65, chlorine found, 57.9%, calcd. 57.4%; (2) backbone #2 copolymer of vinyl chloride and vinyl acetate 87: 13 (Carbide Chemical Company resin VYHH), TI = 0.53; (3) backbone #3, copolymers of vinyl chloride and vinylidene chloride 8 9 : l l (Dow Chemical Company resin X-2716), 7 = 0.64.…”

“…B. mit seitenkettenstandigen H-Si-, Vinyl-Si-und Allyl-Si-Gruppen stellten wir durch Homo-und Copolymerisation der Monomeren, die Monomeren selbst durch Umsetzung von p-Vinylphenyldimethylchlorsilan mit Lithiumaluminiumhydrid bzw. Vinyl-oder Allylmagnesiumhalogeniden herS**Sg)(39) :C H z = C H OAuch das p-Vinylphenyldimethylchlorsilan sowie das daraus durch Hydrolyse einfach zugangliche p-Vinylphenyldimethylsilanol homo-und copolymerisieren mit den verschiedensten Vinylmonomeren gut unter Bildung von organischen Makromolekiilen mit seitenstandigen Chlorsilan-oder Silanol-Gruppen'").Bemerkenswert sind vor allem die Styrolderivate mit Vinyl-Si-und Allyl-Si-Gruppen. Bei ihrer Homo-oder Copolymerisation erhalt man namlich auch bei hohen Umsatzen unvernetzte, losliche Makromolekiile mit ungesattigten seitenstandigen Gruppensg).Dies ist der Tatsache zuzuschreiben, da13 zwar die siliciumstandige pVinylphenylgruppe radikalisch sehr gut polymerisiert, die siliciumstandige Vinyl-und Allylgruppe dagegen nicht.…”
