Renewable Polyester Film having a Low Modulus and High Tensile Elongation

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