Key statement: A process for the preparation of a 1,3-butadiene and styrene copolymer comprising the following steps: a) anionically polymerizing a blend comprising from 5% by weight to 40% by weight of styrene and from 60% by weight to 95% by weight of 1.
Further investigations by our research group revealed that a better approach to obtain epoxy/thiol-ene systems was to anionically polymerize the epoxy resin with allyl-functionalized tertiary amines as curing agents in conjunction with a multifunctional thiol and a radical photoinitiator [32, 33].
By general classification, a CA monomer is an acrylic resin that rapidly polymerizes anionically in the presence of base, forming long, strong polymer chains that bond adjacent substrates together.
The sample has been anionically synthesized and is nearly monodisperse with molecular weight [M.
The addition of BayhydurA XP 2655 or other anionically hydrophilized polyisocyanate hardeners further raises the chemical resistance to the level of modern solvent-free two-component coatings.
Radically prepared polystyrenes are more susceptible to UV degradation than anionically prepared polystyrenes since they contain double bonds, in-chain peroxide linkages, and other oxygen containing groups, all of which increase the UV absorption/reactivity of the internal and external polystyrene matrix.
