    摘要: The invention relates to enamine resins which are the reaction products of a) an acetoacetylated resin, and a C1-C20 alkyl amine or a mixture of C1-C20 alkyl amines. The acetoacetylated resin is the reaction product of a polyol having 4 or more hydroxyl groups; and at least one acetoacetate. The invention also relates to an acetoacetylated resin which is the reaction product of a polyol having 4 or more hydroxyl groups and at least one acetoacetate, where a portion of the hydroxyl groups of the polyol are replaced by acetoacetate groups and the remaining hydroxyl groups are replaced by a saturated monofunctional carboxylic acid ester, unsaturated monofunctional carboxylic acid ester, or a mixture thereof; as well as to enamine resins prepared from these acetoacetylated resins. The invention also relates to curable coating compositions containing such resins or a mixture of those resins, at least one metallic drier compound; and optionally one or more solvents.

    摘要: Polyhexahydrotriazine (PHT) and polyhemiaminal (PHA) materials chemically modified to include thermoplastic polymer bridging groups, and methods of making such materials, are disclosed. The materials are formed by a process that includes heating a mixture comprising i) a solvent, ii) paraformaldehyde, iii) a diamine monomer comprising two primary aromatic amine groups, and iv) a polymer diamine at a temperature of about 20° C. to less than 150° C. This heating step forms a stable PHA in solution, which can be isolated. The PHA includes covalently bonded thermoplastic polymer groups. The PHA is then heated at a temperature of 150° C. to about 280° C., thereby converting the PHA material to a PHT material that includes covalently bonded thermoplastic polymer groups.

    摘要: The present invention is directed to a design of and a method to synthesize polycations for gene (DNA and RNA) delivery. According to this design, the polycations (also said cationic polymers) are formed by polymerization of endogenous monomers bearing sufficient amino groups through degradable bonds with linker molecules. The amino group-bearing monomers are those naturally existing or nontoxic to human body. The linker molecules are those which are not only degradable to nontoxic fragments but also able to release the amino group-bearing monomers in their native state upon degradation. Some examples for the endogenous amino group-bearing monomers are spermine and spermidine (or their derivatives). Examples for the degradable chemical bonds formed between the amino group-bearing monomers are imines. In order to improve degradability or proton sponging effect, low pKa (
