Sulfonated block copolymers having acrylic esterand methacrylic ester interior blocks, and various uses for such blocks, and various uses for such block copolymers

摘要: A sulfonated block copolymer which is solid and non-dispersible in water having at least two polymer end blocks one interior B wherein each a resistant to sulfonation susceptible sulfonation, the do not contain any significant levels of olefinic unsaturation. Each or more segments selected from (i) acrylic esters, (ii) methacrylic (viii) mixtures thereof; comprising polymerized vinyl aromatic monomers unsubstituted styrene monomers, ortho-substituted (iii) meta-substituted (iv) alpha-methylstyrene, (v) 1,1-diphenylethylene, (vi) 1,2-diphenylethylene (vii) thereof.
