    • An adhesive composition, especially suitable for a two- part adhesive system curable via free radical polymerisation comprises; (A) (meth) acrylate ester monomer; (B) chlorinated elastomeric polymer; (C) core-shell impact modifier; and (D) urethane (meth) acrylate oligomer. Example adhesive compositions include urethane (meth) acrylate oligomer (D) derived from (i) a di- or higher isocyanate having at least two isocyanate groups which differ in reactivity; (ii) a chain-extending reagent which has at least two groups selected from hydroxyl and/ or amino groups, each capable of reaction with an isocyanate group of (i); (iii) a hydroxymethacrylate component or hydroxyacrylate component. Also urethane (meth) acrylate oligomers, suitable for use in adhesive compositions, and derived from: (i) a diisocyanate having two isocyanate groups which differ in reactivity; (ii) a chain-extending reagent which is a polyether polyol selected from ethoxylated and propoxylated derivatives of tri- and tetra- functional polyols; and (iii) a hydroxyl (meth) acrylate selected from polyethylene glycol (meth) acrylate and polypropylene glycol (meth) acrylate, are disclosed.
    • 特别适用于通过自由基聚合可固化的两部分粘合剂体系的粘合剂组合物包括: (A)(甲基)丙烯酸酯单体; (B)氯化弹性聚合物; (C)核壳抗冲击改性剂; 和(D)氨基甲酸酯(甲基)丙烯酸酯低聚物。 实例性粘合剂组合物包括衍生自(i)具有至少两个反应性不同的异氰酸酯基团的二异氰酸酯或更高级异氰酸酯的氨基甲酸酯(甲基)丙烯酸酯低聚物(D) (ii)具有至少两个选自羟基和/或氨基的基团的链延长试剂,每个能与(i)的异氰酸酯基团反应; (iii)羟甲基丙烯酸酯组分或羟基丙烯酸酯组分。 也适用于粘合剂组合物的聚氨酯(甲基)丙烯酸酯低聚物,衍生自:(i)具有两个反应性不同的异氰酸酯基团的二异氰酸酯; (ii)扩链试剂,其是选自三官能和四官能多元醇的乙氧基化和丙氧基化衍生物的聚醚多元醇; 和(iii)选自聚乙二醇(甲基)丙烯酸酯和聚丙二醇(甲基)丙烯酸酯)的羟基(甲基)丙烯酸酯。
