A water-soluble film includes a polyvinyl alcohol resin (A) as a main component, wherein the ratio (X.sub.TD/X.sub.MD) of a degree of elongation (X.sub.TD) in the transverse direction (TD) of the water-soluble film to a degree of elongation (X.sub.MD) in the machine direction (MD) thereof when the water-soluble film is floated on the surface of water at 20° C. for 60 seconds is from 1.05 to 1.5. The water-soluble film exhibits reduced curling, exhibits reduced positional shift, and shows satisfactory sealability while forming a package.

A melt-processable water soluble polymer composition having a high Melt Flow Index comprising a blend of a water soluble polymer with at least 15% by weight of the total composition of a hygroscopic salt to act as a lubricant to render the polymer extrudable and/or mouldable, wherein the water content of the salt is of less than 10% by weight, and optionally a solvent polymer plasticizer in a lower amount by weight percent than the hygroscopic salt.

The present invention provides a resin pellet that enables the molding of a molded product exhibiting a tensile breaking strength at the same level as that of a tensile breaking strength of a resin contained in the resin pellet, a manufacturing method for a resin pellet, a molded product, an automobile part, an electronic apparatus part, and a fiber. The resin pellet of the present invention contains a microcapsule encompassing a heat storage material and a thermoplastic resin, in which a content of the heat storage material is 70% by mass or less with respect to a total mass of the resin pellet, and a capsule wall of the microcapsule contains at least one resin selected from the group consisting of polyurethane urea, polyurethane, and polyurea.

A mobile spray dispenser comprises a fluid circulation system and a heating unit. The fluid circulation system has a motorized pump capable of circulating fluid from a fluid reservoir in a high-pressure spray mode and a low-pressure recirculation mode, and of providing the fluid to a sprayer. The motorized pump draws lower power in the low-pressure recirculation mode than in the high-pressure spray mode. The heating unit is disposed within the fluid circulation system to heat the fluid to a target temperature, and comprises a primary heater and a boost heater. The primary heater is configured to be active during both the high-pressure spray mode and the low-pressure recirculation mode. The boost heater is in fluid series with the primary heater, and is configured to be active only during the low-pressure recirculation mode.

The present invention provides methods for preparing the nut waste composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

Crosslinkable polymeric compositions comprising an ethylene-based polymer, an organic peroxide, and an amine-functionalized interpolymer. Such crosslinkable polymeric compositions and their crosslinked forms can be employed as polymeric layers in wire and cable applications, such as insulation in power cables.

The present invention is directed to a process for producing a modified olefin polymer in an extruder having a feed zone, a melting zone, optionally a mixing zone and optionally a die zone, (A) introducing a stream of an olefin polymer into the feed zone of the extruder; (B) introducing a stream of a free radical generator directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (C) introducing a stream of a functionally unsaturated compound directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (D) extruding the mixture in the extruder at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder; and, optionally, (G) passing the melt of the modified olefin polymer through the die zone to a pelletiser.
