A vinyl group Polycarbonate Any of a group of thermoplastics that are linear polyesters of carbonic acid, especially those derived from bisphenol A and phosgene, characterized by high-impact strength, light weight, and flexibility, and used as shatter-resistant substitutes for glass. Vinyl The univa...
305,306 The polymer produced exhibited a large amount of hydroxyl group as a result of base-catalyzed inter- and intramolecular allyl condensation to form cyclic ketone with hydroxyl functional group (Scheme 24). Nevertheless, the synthesis of stereoregular poly(vinyl ketone) has been reported using...
Yttrium alkyl complexes Cp*2YR react with C H bonds of alkenes to form either yttrium allyl complexes or yttrium vinyl complexes. Less substituted alkenes react faster, consistent with prior alkene coordination. The selectivity of the reaction of Cp*2YR with C H bonds is allylic CH3≫vinyl ...
vinyltriethoxysilane, is a vinyl-functional silane that may be used to improve the bond between glass fiber or mineral fillers and resins that are reactive towards the vinyl group. It is also employed to functionalize resins via free radical mechanisms - copolymerization or grafting - and to modify...

In general, the presence of the phenyl group on the C3 carbon leads to a significant increase in lipophilicity, while the allyl group on the iminium moiety determines the opposite effect. Complex 2b, containing three phenyl units, displays the highest Log Pow value (1.4) and was excluded from...
