A process to form coated polymer particles comprising polymer particles formed from a polymer composition comprising an olefin-based polymer, and a coating formed from a coating composition comprising an aqueous metal acid dispersion and an aqueous polysiloxane emulsion, said process comprising the following: mixing together the aqueous metal acid dispersion and the aqueous polysiloxane emulsion to form a dispersion/emulsion mixture; applying the dispersion/emulsion mixture to a portion of the surfaces of the polymer particles to form wet-coated polymer particles; drying the wet-coated polymer particles to form the coated polymer particles. The aqueous metal acid dispersion and the aqueous polysiloxane emulsion may also be applied, individually, in separate steps.

A manufacturing apparatus includes a granulation machine. The granulation machine forms granules by performing extrusion granulation on a granulation material. The granulation machine includes a die. In the die, a die hole that allows the granulation material to pass therethrough is formed. An outlet opening surface of the die hole has a polygonal shape.

A manufacturing apparatus is an apparatus for manufacturing a water absorption treatment material that is composed of a plurality of grains, and includes a granulation machine and a coating machine. The granulation machine granulates a granulation material and thereby forms a granule (core portion) that constitutes each of the grains The coating machine attaches a coating material that contains an adhesive material to a surface of the core portion formed by the granulation machine, and thereby forms a coating portion that covers the surface of the core portion. The granulation machine forms the core portion that has a through hole that extends through the core portion.

Ethylene-vinyl alcohol copolymer composition pellets comprise: an ethylene-vinyl alcohol copolymer, a conjugated polyene, and a predetermined amount of at least one fisheye-suppressing component; wherein pellet surface portions of the ethylene-vinyl alcohol copolymer composition pellets have a conjugated polyene content of not lower than 30 ppb based on the weight of the pellets. Such ethylene-vinyl alcohol copolymer composition pellets are capable of reliably suppressing occurrence of minute fisheyes having a diameter of 200 m or smaller.

Disclosed herein is a resin pellet and a process to make said resin pellet. The resin pellet comprises a major polyester comprising a catalytic titanium compound, and a minor polyester comprising a phosphorus compound. The major polyester is present in a first compartmentalized zone of the resin pellet and the minor polyester is present in a second compartmentalized zone of the resin pellet.

Provided is a resin composition comprising an ethylene-vinyl alcohol copolymer (A), a hydrate-forming metal salt (B), and a polyamide-based resin (C) that inhibits elution of a resin composition layer during hot water sterilization treatment of a multilayered structure including the resin composition layer, while suppressing odor during melt molding of the resin composition. An aromatic polyamide (C1) and an aliphatic polyamide (C2) are used for the polyamide-based resin (C) at a proportion of (C1)/(C2)=55/45-99/1.

Provided is EVOH resin pellet capable of suppressing the occurrence of fish eye even in a resultant monolayer film, and the method for producing the same. The EVOH resin pellet contains a boron compound and the boron amount in a surface portion of the pellet is 1.7 ppm or less. After the EVOH resin pellet is made to contain the boron compound, the EVOH resin pellet is rinsed with a mixture of water and alcohol so that the amount of the boron compound in a surface portion can be reduced.

Disclosed herein is a resin pellet and a process to make said resin pellet. The resin pellet comprises a major polyester comprising a catalytic titanium compound, and a minor polyester comprising a phosphorus compound. The major polyester is present in a first compartmentalized zone of the resin pellet and the minor polyester is present in a second compartmentalized zone of the resin pellet.
