Publication number: 20110294924Abstract: Copolymer are formed by polymerizing C4 to C7 isoolefin monomers and alkyl-styrene monomers. The method comprises first providing feed streams into a reactor. The various feed streams provide monomers, a polar diluent or polar diluent mixture, and a catalyst system into the reactor. In the reactor, the feed streams contact one another so that the monomers form a polymer in a stable slurry, wherein the amount of polymer in the slurry yields a slurry concentration greater than 22 wt %. The ratio of moles of polymer formed per mole initiator is in the range of 0.25 to 4.0 moles polymer per mole of initiator.Type: ApplicationFiled: June 1, 2010Publication date: December 1, 2011Inventors: Timothy D.

Publication number: 20110288219Abstract: Disclosed is layered double hydroxides (LDH) used to catalyze the polymerization of polyethylene terephthalate (PET). The LDH of a catalyst amount may efficiently reduce the PET polymerization period and further be uniformly blended into the PET product to form composites. Compared with the pure PET, the composite including LDH has better properties such as mechanical properties, linear expansion coefficient, barrier, thermal stability, and transparency. In addition, the LDH in the composite is safer than conventional heavy metal catalysts, especially when applied to food or drink packages.Type: ApplicationFiled: August 18, 2010Publication date: November 24, 2011Inventors: Tsung-Yen TSAI, Shao-Wen LU, Wei-Chuan SHIU, Syuan-Ci SU, Tzu-Fang CHEN, Chao-Chen HSU
