Latest Patents
Matsubara's latest patents include a masterbatch composition for thermoplastic resin modification and a method for preparing this composition. The first patent describes a masterbatch composition that contains a polybutene and an ethylene-α-olefin copolymer. This copolymer is obtained by copolymerizing ethylene with α-olefin in the presence of specific catalysts. The composition is characterized by specific properties and can be prepared by kneading and extrusion at a temperature ranging from the maximum peak temperature (Tm) to (Tm-45) degrees Celsius, as determined by differential scanning calorimetry. The resulting masterbatch pellets exhibit low surface tackiness, making them suitable for thermoplastic resin modification.
The second patent outlines a method for preparing masterbatch compositions for thermoplastic resin modification. This method involves blending polybutene with an ethylene-α-olefin copolymer, which is also obtained through copolymerization. The copolymer has specific characteristics, including a density exceeding 0.910 g/cm³ and not exceeding 0.940 g/cm³. The blend is kneaded and extruded within the same temperature range as the first patent, ensuring optimal properties for the final product.
