1-propenyl ethers of butanediol as effective modifiers of UV-cured epoxy coatings in cationic polymerization
Abstract
Models mono- and di-1-propenyl butane-1,4-diol ethers (MoPnE and DiPnE respectively) have been used as modifiers of coatings on the basis of epoxy resin Epidian 6, UV-cured at room temperature in the presence of air and cationic initiators (triarylsulfonium salts containing either SbF6- or PF6- anions). The effects of the type and amount of the ether used as a modifier as well as curing time on glass transition temperature, flexibility hardness and drying time of coatings investigated have been determined. MoPnE appeared to be most reactive modifier because of the presence of two reactive points in the molecule: double bond and primary OH group. This ether can be included into a new class of the monomers active in cationic polymerization of so called monofers.
