Abstract:
1. An actinically-crosslinkable linear polysiloxane copolymer, comprising at least one linear polysiloxane segment end-capped at least at one of the two ends of the polysiloxane segment with one hydrophilic polymer chain through a linkage and at least one ethylenically unsaturated group covalently linked to the linkage, wherein the hydrophilic chains is composed of one or more monomer units selected from the group consisting of units of N-vinyl-2-pyrrolidone (NVP), N,N-dimethylacrylamide (DMA), dimethylaminoethyl methacrylate, dimethylaminoethyl acrylate, vinyl alcohol, dimethylaminoethylmethacrylamide, a C 1 -C 4 -alkoxy polyethylene glycol (meth)acrylate having a weight average molecular weight of from 200 to 1500, N-vinyl-N-methyl isopropylamide, N-vinyl-N-methyl acetamide, and mixtures thereof.
