  • Publication number: 20100147476
    Abstract: Disclosed herein are hydrophobically-modified poly(aminoamides) useful as fixative detackifiers for stickies and pitch control in papermaking processes. These polymers are prepared via modification of amine-containing water-soluble poly(aminoamides) with reactive functional group-containing hydrophobic compounds. In particular, poly(aminoamides) may be modified, under appropriate reaction conditions, with long chain alkyl glycidyl ether, AKD (alkyl ketene dimer), ASA (alkyl succinyl anhydride), or Quab (3-chloro-2-hydroxypropyl-N,N,N-dimethylalkyl ammonium chloride). These novel polymers are effective in inhibiting deposition of organic contaminants in pulp and papermaking systems.

  • Publication number: 20100152407
    Abstract: Ketimines, enamines and oxazolidines are moisture labile functional groups that in the presence of water undergo hydrolysis to yield free amines. Within the art such latent amines have found utility in curable compositions where it is desirable to initiate cure in the presence moisture. A number of novel polyketimines, polyenamines, polymeric oxazolidines and oxazolidines are disclosed. In particular, polymeric compounds of the above classes derived from C6 cyclic diketones and polyamines are reported. Suitable C6 cyclic diketones include cyclohexanediones and quinones. The invention further relates to the applications of the materials, such as in moisture cure adhesives.

  • Patent number: RE43880
    Abstract: This invention relates to the composition and a solvent-free process for preparing novel imide oligomers and polymers specifically formulated with effective amounts of a dianhydride such as 2,3,3?,4-biphenyltetra carboxylic dianydride (a-BPDA), at least one aromatic diamine and an endcapped of 4-phenylethynylphthalic anhydride (PEPA) or nadic anhydride to produce imide oligomers that possess a low-melt viscosity of 1-60 poise at 260-280° C. When the imide oligomer melt is cured at about 371° C. in a press or autoclave under 100-500 psi, the melt resulted in a thermoset polyimide having a glass transition temperature (Tg) equal to and above 310° C. A novel feature of this process is that the monomers; namely the dianhydrides, diamines and the endcaps, are melt processable to form imide oligomers at temperatures ranging between 232-280° C. (450-535° F.) without any solvent.
