A first mixture is formed by mixing a water-absorbing filler with a hydrous filler containing water in advance and adsorbing the water on the water-absorbing filler, then a second mixture is formed by mixing the first mixture with synthetic resin, then a melted and kneaded product is formed by feeding the second mixture into a closed container and heat-kneading the second mixture at a temperature at which the synthetic resin melts, and then the water contained in the melted and kneaded product is discharged to the outside by opening the closed container.

The present disclosure provides a method for preparing a vinyl chloride-based polymer, the method including a step of injecting an ionizable normal salt and polymerizing a vinyl chloride monomer in the presence of one or more emulsifiers and a polymerization initiator, wherein the ionizable normal salt includes a carbonate metal salt or a sulfite metal salt, and the ionizable normal salt is continuously injected in an amount of 70 to 1200 ppm based on the total weight of the vinyl chloride monomer when a polymerization conversion rate is in a range of 0% to 20%. The method capable of preparing a vinyl chloride-based polymer suitable as an eco-friendly material, while not affecting the rate of polymerization reaction and decreasing the generation amount of total volatile organic compounds by controlling the injection time, injection amount and kind of the ionizable normal salt, is provided.

Disclosed are powder coating compositions that include a polymeric aromatic product of an aromatic isocyanate manufacturing process.

The lightweight footwear of the present invention maintains excellent durability and improves heat resistance, so that contraction percentage due to a change with the passage of time is significantly low, rarely causing deformation, and thus, the lightweight footwear may be used in a high temperature and sanitary environment. In addition, the present invention solves the problem of the occurrence of premature foaming due to injection molding and a pattern on the appearance due to dispersion failure, thereby facilitating injection molding.

The present disclosure provides a low-smoke, non-halogenated flame retardant composition made from or containing (a) a first ethylene/vinyl acetate copolymer, having a total content of vinyl acetate-derived units in an amount from about 15 to about 45 weight percent, based upon the total weight of the ethylene/vinyl acetate copolymer; (b) a coupling agent; (c) magnesium dihydroxide; (d) hydromagnesite; and (e) huntite.

Compositions useful as coatings for wire and cable comprise, in weight percent (wt %) based on the weight of the composition: (A) 10 to 62 wt % of a silane-grafted ethylene polymer (Si-g-PE) having a silane content of 0.5 to 5 wt % based on the weight of the Si-g-PE, wherein the Si-g-PE is made from an ethylene polymer (base resin) having the following properties. (1) Density of 0.875 to 0.910 g/cc; (2) Melt index (MI, 12) of 8 to 50 g/10 min (190 C./2.16 kg); and (B) 38 to 90 wt % of a halogen-free flame retardant (HFFR); (C) 0 to 0.3 wt % of an antioxidant; and (D) 0 to 1 wt % of a silanol condensation catalyst.

A process for the preparation of a film is described, in which a substrate is coated with a coating mixture containing a water-soluble polymer and a layered double hydroxide. The process of the invention is markedly simpler that conventional techniques for affording films having reduced permeability to degradative gases. The films obtainable by the process are particularly useful in packaging applications, notably in the food industry.

A polymer processing aid (PPA) reduces melt defects in extruded polyolefins in the absence of fluoropolymers. The polymer processing aid comprises a polyalkylene glycol such as a polyethylene glycol together with a high pressure low density polyethylene (LDPE) and reduces melt defects well in a thermoplastic polyolefin such as a linear low density polyethylene (LLDPE).

A polymer composition for producing gel extruded articles is described. The polymer composition contains polyethylene particles combined with a plasticizer and an acid scavenger. In accordance with the present disclosure, the acid scavenger is an inorganic compound that is insoluble in the plasticizer and/or any extractions solvents used during the process. In one embodiment, the acid scavenger is a magnesium aluminum hydroxide carbonate.
