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.
摘要(中):
描述了聚合物珠粒的分散体,其中珠粒包含共聚物组合物,其包含(优选基本上由以下组成):共聚物(及其制备方法),其包含(a)至少8.5重量%,优选> = 20重量% 衣康酸二酯(衣康酸二丁酯-DBI)较高; (b)小于23重量%的酸单体,但也足以使酸值小于150mg KOH / g的聚合物,(c)任选地含有少于50重量%的其它衣康酸酯单体,和(d)任选地 不超过77重量%的其它单体(a)至(c)。 DBI可能是biorenewable。 另一个实施方案是用于由烯属不饱和单体和自由基引发剂制备乙烯基聚合物珠的水悬浮聚合方法,其中至少10重量%的单体是DBI。
