Claim Text:
1. An oligomer-polymer composition comprising an oligomer composition O having a weight average molecular weight of from 1000 to 150,000 g/mol (measured by GPC), and a polymer composition P having a weight average molecular weight of at least 80,000 g/mol (measured by GPC), wherein the oligomer composition O and the polymer composition P each independently comprise a copolymer comprising: (a) optionally at least 23% by weight of at least one monomer represented by Formula 1:  where both R (b) optionally at least one hydrophilic monomer in an amount sufficient that the resultant copolymer has an acid value less than 150 mg KOH per g of polymer, (c) optionally of one or more monomers represented by Formula 2:  where R  X  with the proviso that when X (d) optionally less than 77% by weight of monomers other than components (a), (b) or (c), where the percentages or amounts of (a), (b) (c) (d) are by weight calculated as a proportion of the total weight of (a)+(b)+(c)+(d) and thus total 100%; where independently at least one of the components (a), (b), (c), (d) and the copolymer obtained from components (a), (b), (c) and/or (d) is biorenewable as defined by an amount of carbon-14 sufficient to produce a decay of at least about 1.5 disintegrations per minute per gram carbon (dpm/gC); and where at least one component (a) is present in either oligomer composition O or polymer composition P, and wherein the oligomer-polymer composition comprises: (a) component (a) in an amount from 24% to 70% by weight being one or more monomers represented by Formula 1 (b) component (b) being one or more acid functional monomer(s) in an amount from 0.5% to 15% by weight, in an amount also sufficient that the resultant copolymer has an acid value of from 3 to 100 mg KOH per g of polymer, (c) component (c) in an amount from 0.01% to 10% by weight being one or more monomers represented by Formula 2 in which X (d) component (d) if present in an amount less than 75% by weight of monomer(s) other than components (a), (b) or (c) not containing styrene, butyl acrylate, 2-ethyl hexyl acrylate and/or mixtures thereof; and with the provisos that
