摘要:
A process for obtaining an aqueous emulsion comprising a block copolymer by the solution polymerisation of vinyl monomers to obtain block [B] in the presence of a) a radical precursor; and b) an iodine atom containing block [A]; where block [A] and [B] together comprise 0 to 2 wt % of methacrylic acid; where block [A] and block [B] together comprise ≧2.5 wt % of vinyl monomers bearing ionic or potentially ionic water-dispersing groups not including methacrylic acid; and performing a post polymerisation reaction on the block copolymer emulsion obtained in step II; and wherein said aqueous emulsion has a free vinyl monomer level
摘要:
A radiation curable liquid coating composition comprising 1 to 90 wt % of at least one multifunctional (meth)acrylated oligomer; 10 to 80 wt % of at least one C8 to C20 monofunctional aliphatic alkyl (meth)acrylate; 0 to 40 wt % of at least one monomeric reactive diluent wherein (a)+(b)+(c)=100%; and additionally comprising 0.1 to 15 wt % of matting agent by weight of the coating composition.
