    • According to the present invention, curable compositions comprising (i) one or more polyacid containing at least two carboxylic acid groups, anhydride groups, or salts thereof; (ii), optionally, one or more polyol containing at least two hydroxyl groups; and (iii) one or more reactive β-hydroxyamide group containing polyol, which is the reaction product of a lactone or cyclic ester and an alkanolamine, of the following formula (I): in which, R and R″ independently represent H, or any monovalent C1 to C18 linear or branched alkyl radical, which radical may comprise one or two aryl or cycloalkyl group, one or more hydroxyl, amine, thiol, amide, carboxyl or alkenyl group, or combinations thereof; R′ represents either a covalent bond or a divalent C1 to C5 alkylene radical where the alkylene radical may bear alkyl group substituents; y is the integer 1 or 2; x is 0 or 1, such that (x+y)=2; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to 1/3. The curable compositions of the present invention provide less corrosive, low energy curing binders. Further, the present invention provides methods to use the compositions as aqueous binders for composites, nonwoven and woven substrates, and the products produced thereby.

    • The present invention provides wood adhesive binder compositions comprising a naturally occurring protein component, e.g. soy flour, and an oxazoline-functional group containing polymer or resin component, the two components in a solids weight ratio of from 60:40 to 98:2. As formulated, the compositions may comprise from 40 to 98 wt. % of the naturally occurring protein component, preferably, 50 wt. % or more. Preferably, the wood adhesive binder further comprises lignins or lignosulfonate. Where the wood adhesive binder compositions comprise lignins or lignosulfonates, they remain more fluid and workable at a higher pH such as, for example, 4.5 or more. Any of the compositions may be formulated with one or more in situ acid generator compound to insure more rapid cure on heating or pressing. The binder enables the provision of mechanically sound, low cost and biodegradable composites, such as, medium density fiberboard (MDF).
    • 本发明提供了包含天然存在的蛋白质组分的木粘合剂粘合剂组合物, 大豆粉和含恶唑啉官能团的聚合物或树脂组分,固体重量比为60:40至98:2的两种组分。 如所配制的,组合物可以包含40至98wt。 %的天然存在的蛋白质组分,优选50重量% % 或者更多。 优选地,木材粘合剂粘合剂还包含木质素或木质素磺酸盐。 在木材粘合剂粘合剂组合物包含木质素或木质素磺酸盐的情况下,它们保持更高的流动性并且在较高的pH例如4.5或更高的pH下可使用。 任何组合物可以用一种或多种原位酸发生剂化合物配制,以确保在加热或加压下更快速固化。 粘合剂能够提供机械声音,低成本和可生物降解的复合材料,例如中密度纤维板(MDF)。
