Coordination polymerization of polar vinyl monomers by single site metal catalysts.

Vinyl ethers polymerization.

Journal of the american chemical society 2010 132 14 5273 5284. Titanium complexes of α α α α tetraaryl 1 3 dioxolane 4 5 dimethanol taddol derived from naturally abundant tartaric acid were demonstrated to function as highly effective catalysts for the stereoselective cationic polymerization of vinyl ethers ves. In general vinyl ethers possessing highly branched alkyl groups are more reactive than those bearing straight chain alkyl groups. Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics.

It can be initiated with peroxide azo and redox initiators. Isotactic poly isobutyl ve m 90 was generated via polymerization using an initiating system prepared by simply mixing taddol ticl 4 and isobutyl ve monomer. We identified the cationic polymerization of vinyl ethers as a high value target to exemplify such a catalyst controlled approach. Degenerative chain transfer polymerization of vinyl ethers by simply using mixtures of weak and superstrong protonic acids.

Chinese journal of polymer science 2019 37 9 851 857. Poly vinyl ether s with a t g as high as 100 c have been obtained in the living cationic polymerization of vinyl ethers with a bulky tricyclodecane or tricyclodecene unit using hcl zncl 2 in toluene at 30 c. 124 the fast living cationic polymerization of vinyl ethers with sncl 4 combined with etalcl 2 in the presence of an ester as an added base was reported. 125 the cationic polymerization of vinyl ethers with a urethane group 4 vinyloxybutyl n butylcarbamate and 4 vinyloxybutyl.

A user friendly living cationic polymerization. Poly vinyl ether s pves feature a polar ether functionality in. Living cationic polymerization tfa et 2 alcl 1 4 dioxane of the vinyl ether functionalities afforded linear poly ve s which were then subjected to polymerization involving the acetylene moieties by either cu catalyzed oxidative coupling or a rh catalyzed process with both catalytic systems promoting formation of brush shaped polymers. Vinyl ethers undergo homopolymerization via a cationic mechanism.
