    • Curable compositions include at least one monomer compound having both (meth)acrylic ester functionality and an allylic phenyl ether functional group on the same molecule, the allylic phenyl ether functional group having at least one unsubstituted position on the phenyl ring which is ortho or para to the allylic ether group, and a free radical catalyst system. The composition may also includes a latent thermally activated acid generator. Claisen Rearrangement of radically polymerized polymers produced from the compositions may be induced at temperatures of about 100° C. or more to give crosslinked products of improved thermal resistance. Novel monomers which may be used in such compositions are characterized by formulas I and II: where R1 is H or methyl; R2 is a direct bond, a group of the formula —NCnH2n-, or a group of the formula —(OCnH2n—)m— which when taken with the phenyl group to which it is attached forms a phenyl ether; n is 1-4 and m is 1-10; R3 is —CH2CH═CH2, —CH2C(CH3)═CH2, —CH2CH═CH(CH3), —CH2C(CH3)═CH(CH3), —CH2CH═C(CH3)2 or —CH2 CH═CH(C6H5); and R4 is a divalent allylic group, and wherein the compound is optionally substituted on a phenyl group thereof by an alkyl, alkoxy or halo group, provided that relative to the respective —OR3 or —OR4O — groups, at least one unsubstituted ortho or para position remains on an adjacent phenyl ring.

    • In accordance with the present invention, there are provided toughening agents which are useful for improving the performance properties of epoxy-based adhesive formulations. For example, epoxidized polybutylacrylates have been found to be useful toughening agents of component level underfill adhesive compositions. Invention materials are generally liquid rubbers which provided improved fracture toughness while maintaining satisfactory capillary flow properties. Invention materials can be synthesized in neat (solventless) reactions from readily available low-cost raw materials and isolated in high yields. They have a branched telechelic structure with terminal epoxide functional groups. The polyacrylate is typically obtained as a mixture of epoxidized polymer, chain extended polyoligomer and unreacted monomer. Invention materials are compatible with common epoxy formulations and may be used without purification. At low levels of incorporation, they provide adhesives that meet the minimum fracture toughness (Gq>2.0 lb/in) and capillary flow specifications (flow time
    • 根据本发明,提供了可用于改善环氧基粘合剂制剂的性能的增韧剂。 例如,已经发现环氧化的聚丁基丙烯酸酯是组分级底部填充粘合剂组合物的有用的增韧剂。 发明材料通常是液体橡胶,其提供改善的断裂韧性同时保持令人满意的毛细管流动性能 本发明材料可以从易于获得的低成本原料的纯(无溶剂)反应中合成并以高收率分离。 它们具有末端环氧官能团的分子遥爪结构。 聚丙烯酸酯通常以环氧化聚合物,链延长多元寡聚物和未反应单体的混合物形式获得。 本发明材料与普通的环氧配方相容,可以不经纯化地使用。 在低掺量下,它们提供了许多商业底层填充应用的粘合剂,其满足最小断裂韧性(Gq> 2.0lb / in)和毛细管流动规格(流动时间<180秒)。 根据本发明的另一个实施方案,提供了包含本发明化合物的粘合剂组合物及其使用方法。 在本发明的另外的实施方案中,提供了制备本发明增韧剂的方法,用于将装置粘附到基底上的方法以及包括附着到第二制品上的第一制品的组件。
