Polymer Comprising Certain Level Of Bio-Based Carbon

A polymer comprising:

• (a) from 40 mol-% to 99 mol % repeating units according to Formula (1), wherein at least 10 wt.-% of the repeating units according to Formula (1) comprise from 28 wt.-% to 100 wt.-% bio-based carbon content, relative to the total mass of carbon in the repeating unit according to Formula (1), measured according to standard ASTM D6866-12, Method B;
• wherein:
• R1 and R2 are independently selected from the group consisting of H, methyl and ethyl;
• A is a linear or branched C1-C12-alkyl group;
• and Q+ is H+, NH4+, organic ammonium ions [NHR5R6R7]+ wherein R5, R6, and R7 independently of one another may be hydrogen, a linear or branched alkyl group having 1 to 22 carbon atoms, a linear or branched, singularly or multiply unsaturated alkenyl group having 2 to 22 carbon atoms, a C6-C22 alkylamidopropyl group, a linear mono-hydroxyalkyl group having 2 to carbon atoms or a linear or branched dihydroxyalkyl group having 3 to carbon atoms, and where at least one of the radicals R5, R6, and R7 is not hydrogen, or Q+ is Li+, Na+, K+, ½ Ca++, ½ Mg++, ½ Zn++, ⅓ Al+++, or combinations thereof;
• (b) from 0.01 mol-% to 5 mol % of crosslinking or branching units, wherein the crosslinking or branching units result from the incorporation of a monomer comprising at least two olefinically unsaturated double bonds;
• (c) from 0.99 mol-% to 59.99 mol % of repeating neutral structural units, wherein at least 10 wt. % of the neutral structural units comprise from 0 wt.-% to 100 wt.-% bio-based carbon content, relative to the total mass of carbon in the repeating unit (c), measured according to standard ASTM D6866-12, Method B.
