Abstract

Coatings obtained through photopolymerisation of vinylethers, propenyl ethers and epoxy resins are described. The influence of alcohols and of comonomers bearing OH groups on the cationic mechanism of the curing process is discussed. The final properties of the coatings are evaluated and correlated to the structures of the additives.

Fluorinated Hyperbranched Polymers as Additives in Cationic Photopolymerization

“…In recent studies from our group12 hydroxyl containing additives were employed as chain transfer agents in cationic photopolymerization, with the purpose of improving the curing process and the final properties of cured films.…”

Fluorinated networks through photopolymerisation processes: synthesis, characterisation and properties

“…Therefore, the monofunctional monomer is more surface active: in fact its fluorinated chain is freely dangling from the network; moreover it contains a perfluoromethyl as an end group which guarantees a very low surface energy as described in Zisman's work [31]. At present, investigations are carried out on the effect of the end groups on the surface activity of the PFPE chains: perfluoromethyl, difluoro-chloro-methyl and difluoro-methyl end groups are compared [32].…”

VUV‐Induced Photopolymerization of Acrylates

“…In the latter case, N -substituted maleimides are widely used as acceptor monomers whereas vinyl ethers, [5][6][7][8][9][10][11] alkoxystyrenes, [ 6 , 7 ] or N -vinylpyrrolidone [ 7 , 12 ] serve as electron donors. Moreover, maleimides and bismaleimides can be copolymerized with diacrylates [13][14][15] via hydrogen abstraction from the triplet state of excited maleimides.…”
