Abstract: A method of making a film and the resulting film are disclosed. A matrix polymer comprising at least 20 wt. % nylon-6 is combined with moisture-absorbing particles and mixed in an extensional flow mixer to disperse the moisture-absorbing particles in the matrix polymer. The mixed composition is formed into a film comprising at least 20 wt. % matrix polymer and 1 wt. % moisture-absorbing particles. The film is oriented in at least one direction by a ratio of at least 1.2:1 to provide an unperforated, oriented film having a thickness of at least 20 microns and a water transmission rate of at least 24 g/m2/hr. The film is useful in food casing applications.

Abstract: A method of incorporating an additive into a polymer composition includes the step of melt blending a polymer with a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step. The dispersion is also described.

Abstract: Disclosed is a thermoplastic resin composition containing a graft material and an organic peroxide group dispersion medium in which the graft material is dispersed. The graft material is obtained by melt-mixing a metal oxide fine particle having an organic peroxide group on the surface and a thermoplastic resin, and has a structure in which the thermoplastic resin is grafted to the metal oxide fine particle. The organic peroxide group on the surface of the metal oxide fine particle is preferably a peroxymonocarbonate group. The organic peroxide group on the surface of the metal oxide fine particle is preferably obtained by reacting a hydroxy group of a silicon oxide fine particle with an amino-modified silane coupling agent, thereby introducing an amino group to the surface of the silicon oxide fine particle, and then reacting the amino group with a compound having an ethylenically unsaturated group and an organic peroxide group.

Abstract: Polyglycolic acid and polylactic acid having a weight-average molecular weight of at most 50,000 are melt-kneaded in the presence of a thermal stabilizer to obtain a polyglycolic acid-based aliphatic polyester composition. The aliphatic polyester composition alleviates the too fast crystallizability of polyglycolic acid which has been problematic in forming or molding of polyglycolic acid alone or in combination with another thermoplastic resin, thus showing a crystallization speed which has been lowered and can be controlled in a wide range.
