  • Patent number: 8980964
    Abstract: A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.

  • Patent number: 8883882
    Abstract: The invention relates to a non-aqueous dispersion of organic polymer particles in a reactive diluent. Said non-aqueous dispersion can be obtained in that at least one monomer is polymerized in the reactive diluent, forming the organic polymer particles, wherein the reactive diluent does not participate in said polymerization due to the orthogonal reactivity thereof relative to the monomers, but comprises a functionality allowing later targeted polymerization. Depending on the organic polymer particles or reactive diluents used, the non-aqueous dispersion can be used in multifaceted applications having a wide range of application profiles. In order to produce said non-aqueous dispersion, polymerization of at least one monomer in a stirred tank reactor in the presence of a reactive diluent is particularly suitable, wherein the conversion is performed at a stirring speed of at least 2 m/s, wherein the ratio of the stirrer diameter to the vessel diameter is set to 0.3-0.
