POLYMERIC BEADS, PROCESS AND COMPOSITION |
摘要 |
There are described a dispersion of polymeric beads where the beads comprise a copolymer composition comprising (preferably consisting essentially of):copolymers (and processes for making them) comprising (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. A further embodiment is an aqueous suspension polymerisation process for preparing vinyl polymer beads from olefinically unsaturated monomers and a free-radical initiator, where at least 10 wt-% of the monomer is DBI. |
