Abstract: Disclosed herein is a method for producing isotropized “ready-to-use” polymer pellets or granules that contain completely or substantially relaxed matrix molecules and entangled organic nanofibrils with long aspect ratios that will provide superior properties for the products without high cost. These pellets are cost-effectively produced using industrial-scale fiber spinning or melt-blowing/spun-bond equipment followed by an isotropizing pelletizer. These pellets enable one to mass-produce the micro-fibrillar or nanofibrillar composites with superior mechanical properties, because they are readily usable (“ready-to-use”) for industry-scale mass production systems with a very high throughput over 1000 kg/hr. The organic nanofibrils are well dispersed and entangled in the polymer matrix and have a long aspect ratio ranging hundreds to thousands, to tens of thousands. The nanofibrils are entangled with each other to have proper rheological properties for film or foam processing, and to have good mechanical properties of the final products.

Abstract: A kneader includes a kneader main body including a casing including a kneading chamber and a kneading portion that is disposed in the casing and kneads a material in the kneading chamber. The material supplied to the kneading chamber includes a resin material, an inorganic additive added to the resin material, and a coupling agent for enhancing affinity of the inorganic additive for the resin material. The kneader further includes a kneading monitoring portion that monitors a kneading state of the material by detecting a reaction product that is generated by a reaction between the coupling agent and the inorganic additive.

Abstract: A multi-shaft kneading machine includes a channel and two screws rotatable around first axes of rotation. A pair of gate rods sandwich the two screws and are rotatable around second axes of rotation. Each of the pair of gate rods has two recess parts that form respective spaces through which the two screws penetrate. Each of the pair of gate rods has a first contact surface, which comes into surface contact with a screw when a gate rod is rotated to a minimum degree-of-opening position. Large diameter parts are fitted into the groove of the cylinder, and a small diameter part have a radius of curvature equal to half a distance between two second axes of rotation and smaller than a radius of curvature of the large diameter parts. The small diameter parts of the pair of gate rods are in contact with each other.
