    摘要: Resins which comprise polymers which contain multiple acetal groups have been developed which are useful for crosslinking and adhesion promotion in coating and adhesive applications. The polymers which make up these resins are prepared by the addition of aminoacetals to polymers containing anhydride functionality. The polymers are modified by titration with ammonia or a primary or secondary amine which solubilizes the polymer in aqueous systems.

    摘要: Resins which comprise polymers which contain multiple acetal groups have been developed which are useful for crosslinking and adhesion promotion in coating and adhesive applications. The polymers which make up these resins are prepared by the addition of aminoacetals to polymers containing anhydride functionality. Optionally, these polymers may be modified by titration with a tertiary amine or alkali base which solubilizes the polymer in aqueous systems.

    摘要: This invention relates to a class of tertiary-alkyltoluenediamines having alkyl groups ortho to an amine group. More particularly the aromatic diamines are represented by the formulas: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are C.sub.1-3 alkyl groups or R.sub.2 and R.sub.3 are combined to form a C.sub.5-6 membered ring.The above described alkylated aromatic diamines have been found to be well suited for use as a chain extender in forming polyurethane/urea elastomer systems and the mono tert-butyltoluenediamine isomers have been found to be nonmutagenic in the Ames test.

    摘要: N,N'-Di-(branched alkyl)-alkylenediamine-bis-p-aminobenzamides are useful as chain extenders in the manufacture of polyurethane-urea elastomers. These compositions have remarkably uniform reactivities but can be varied structurally to achieve a range of processibility characteristics by altering the melting points of the chain extenders. The preferred compounds melt in a range of 50.degree. to 175.degree. C. while exhibiting t.sub.5000 reactivities of about four minutes. The combination of processing characteristics, reactivities and physical properties of the elastomer products offers advantages not available in commonly used diamine chain extenders of the prior art.
