  • Publication number: 20140147604
    Abstract: The invention concerns a heat-sealable biodegradable packaging material, which comprises a fibrous substrate (1) and one or more polymer coating layers (2) extruded onto said substrate. According to the invention the packaging material includes at least one polymer coating layer (2) containing at least 70 weight-% of polylactide (PLA) and at least 5 weight-% of polybutylene succinate (PBS) or its derivate blended therewith. Optionally an acryl copolymer such as ethylene butyl acrylate glycidyl methacrylate terpolymer (EBAGMA) may be included in the polymer blend. The invention further concerns a heat-sealed container, such as a disposable drinking cup, and a heat-sealed product package made from the packaging material, as well as uses of PBS or its derivates as blends with PLA in extrusion coating, for improving adhesivity of the coating to the fibrous substrate and reduced raw edge penetration to the packaging material, especially penetration of hot coffee held in the drinking cup.

  • Patent number: 8735496
    Abstract: The present invention relates to a process for the production of the largest possible spherical, monodisperse polyvinylpyrrolidone (PVP) seed particles in the micron range by dispersion polymerisation. The particles obtained in this way represent novel starting materials for the production of macroporous polymer particles, which can in turn be employed in preparative and analytical chromatography for protein preparation. They can also be employed as base material for further reactions. The novel process for the polymerisation of N-vinylpyrrolidone, which is inexpensive to carry out, gives particles having optimised quantities, such as monodispersity, sphericity and particle diameter, which can be employed in further reactions and have advantageous, in particular improved, properties for use in chromatographic separation methods.

  • Patent number: 8637130
    Abstract: A molded part that is formed from a thermoplastic composition that contains a polylactic acid, propylene/?-olefin copolymer, and a polyolefin compatibilizer is provided. The propylene/?-olefin copolymer can be dispersed as discrete physical domains within a continuous matrix of the polylactic acid. Without intending to be limited by theory, it is believed that the discrete domains can help resist the expansion of the composition during a molding operation, which minimizes the degree of expansion experienced by the composition during molding in comparison to conventional polylactic acid compositions.
