  • 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.

  • Publication number: 20140249242
    Abstract: The present invention relates to a novel type of grafting or crosslinking method for (meth)acrylates in which the reaction is initiated by isocyanates and specific bases having an imine structure. Using this novel and specifically applicable method, polymers, particularly polyolefins having double bonds, may be grafted or crosslinked in a suitable reaction procedure. Furthermore, these unsaturated polymers may be used, following reaction with (poly)isocyanates, to prepare graft or block copolymers or also for the bonding of the modified unsaturated polyolefins to polyamides, polyesters, polycarbonates, polyimines or polyurethanes.
