    Abstract: There is described use of a biorenewable copolymers in one or more of: in a topical and/or personal care composition, as a binder for toner, as an encapsulating agent for a colorant, as a hybrid colorant, as additive for sheet moulding compounds, as a plastic pigment, as a filler for composite materials such as concrete, as a filler for coatings and/or waxes; and/or as a spacer in a display; where the biorenewable copolymer comprises (a) at least 8. 5 wt-% preferably >=20 wt-% of a higher itaconate diester (preferably dibutyl itaconate—DBI); (b) less than 23 wt-% acid monomer but also sufficient to have an acid value less than 150 mg KOH/g of polymer, (c) optionally with less than 50 wt-% of other itaconate monomers, and (d) optionally less than 77 wt-% of other monomers not (a) to (c). The DBI may be biorenewable. One embodiment is an aqueous dispersion of vinyl sequential polymer of two phases: A) 40 to 90 wt-% of a vinyl polymer A with Tg from −50 to 30° C.; and B) 10 to 60 wt-% of a vinyl polymer B with Tg from 50 to 130° C.; where DBI is used to prepare A and/or B and polymer A has from 0.1 to 10 wt-% of at least one acid-functional olefinically unsaturated monomer.

    Abstract: The present invention relates to an aqueous polymer emulsion comprising at least 30 wt. % of a vinyl copolymer (A), said vinyl copolymer comprising: (I) from 10 to 90 wt. % of 2-octyl acrylate monomer; (II) from 10 to 90 wt. % of at least one itaconate ester monomer according to formula (1) in which A and B may be different or the same and A and B are independently an alkyl group or an aryl group; and (III) from 0 to 80 wt. % of ethylenically unsaturated monomer other than (I) and (II); whereby the summed amount of (I), (II) and (III) is 100 wt. % and whereby the amount of vinyl copolymer (A) is given relative to the total weight amount of the polymers present in the emulsion.
