Abstract:
An uncured polymeric resin composition comprising a polymer chain made up of segments having the general formula: ##STR15## wherein MN denotes a section of the polymeric backbone which is saturated or unsaturated;wherein the arrows denote that the pendant groups are attached to the backbone at any point, and that varying quantities of the pendant groups are present in each of the sections of each molecule of the polymeric resin;wherein Z is a hydrocarbyl which does not substantially interfere with crosslinking hydrophilicity or stability of the composition, and where a is 0 or 1;wherein R.sub.1 is selected from the group consisting of A' and B',where A' is ##STR16## where R' is an acrylate moiety ##STR17## or a vinyl ether moiety --R--O--CH.dbd.CH.sub.2 ; where R is C.sub.1 -C.sub.20 alkyl or aryl which does not substantially interfere with the crosslinking, hydrophilicity or stability of the composition;Y is --O, --N or --S; andwhere V.sup.+ is an alkali metal or alkaline earth metal ion or ammonium ion which does not substantially interfere with the hydrophilicity of the composition, or is H.sup.+ R'""where R'"" is R'- or R""-substituted amine or phosphine;where R"" is an acrylate moiety having 2 to 12 acrylate groups and which does not substantially interfere with the stability of the composition; andwhere B' is ##STR18## where R', Y and V.sup.+ are set forth above, n is 0-10; and wherein R.sub.2 is selected from the group consisting of A"" and B""where A"" is ##STR19## where R"", Y, and V.sup.+ are as set forth above, and B"" is ##STR20## where R"" and Y are as set forth above and n is 0-10.
