Abstract
(Meth)acrylate-based reactive diluent compositions can be used for enabling styrene-free curing of unsaturated polyester resins. The reactive diluent compositions have a (meth)acrylic acid ester monomer and a compatibilizing agent including at least one (meth)acrylate moiety and at least one additional ethylenically unsaturated moiety.
Claims19
A reactive diluent composition, comprising:
- a (meth)acrylic acid ester monomer and a compatibilizer;
- wherein the (meth)acrylic acid ester monomer is at least one selected from the group consisting of methyl methacrylate, glycerol formal methacrylate, isopropylidene glycerol methacrylate, benzyl methacrylate, cyclohexyl methacrylate, isobornyl methacrylate, 1,4-butanediol dimethacrylate, 1,3-butanediol dimethacrylate, polethyleneglycol 200 dimethacrylate, ethylene glycol dimethacrylate, butyl diglycol methacrylate, and ethyltriglycol methacrylate,
- wherein the compatibilizer comprises at least one (meth)acrylate moiety and at least one additional ethylenically unsaturated moiety and is at least one selected from the group consisting of vinylether (meth)acrylates, allylether (meth) acrylates, and alkenyl (meth)acrylates,
- wherein the (meth)acrylic acid ester monomer and the compatibilizer are different chemical compounds, and
- wherein a ratio of an amount of (meth)acrylic acid ester monomer to an amount of compatibilizer is between 1:1 and 70:1.
