  • Patent number: 6027818
    Abstract: Copolyether ester elastomers are provided which contain epoxide compounds. The compositions show improved bloom resistance in the presence of diamines with minimum increase in melt viscosity. Also disclosed are methods to improve appearance and eliminate bloom from finished products comprising thermoplastic copolyesters by lowering the level of acid terminated oligomers in the thermoplastic copolyesters with epoxide compounds.

  • Patent number: 4021400
    Abstract: Compositions containing copolymers of ethylene, alkyl acrylate and monoalkyl esters of 1,4-butenedioic acid and compounds having the formula ##STR1## formed by reacting the minor amount of alkyl acrylate monomer entrained in the copolymer with a secondary amine of the formula ##STR2## are less odorous than are compositions containing the unreacted alkyl acrylate monomer.

  • Patent number: 4016349
    Abstract: Vanadium catalyst residues can be removed from solutions of organic solvents of homopolymers of .alpha.-olefins or their copolymers with hydrocarbon monomers by first contacting at a temperature of about room temperature to about 140.degree. C. the polymer solutions with polar liquid extractants supported on an inert, finely divided, solid material, such as diatomaceous silica, silica gel, alumina, or molecular sieves, then separating the solution from the solid material. Water is the preferred polar liquid, and diatomaceous silica is the preferred supporting material. Polymers recovered from solutions treated according to the process of this invention have a much lesser proportion of vanadium contaminants than those recovered from untreated solutions. This vanadium removal process is simple and inexpensive.
