  • Patent number: 8580898
    Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜50 mol % of a diol compound expressed as HO—(CH2)a—CO—(CH2)b—OH (where a and b are integers in the range 1˜5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol % based on dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage stress.

  • Patent number: 8501308
    Abstract: Thermoplastic polymer compositions, films, continues, closures, laminates can comprise a modified vinyl polymer said modified polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, locked into the polymer structure, can absorb impurities, permeants, or other undesirable volatile materials. The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.

  • Patent number: 8487049
    Abstract: A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.
