Abstract: A microcapsule is produced by dispersing a liquid organic dispersion in an aqueous medium to form a capsule particle in the aqueous medium, the liquid organic dispersion containing an acid group-containing resin, a colored particle and an organic solvent, and the capsule particle comprising a disperse system containing the liquid organic dispersion, and a wall encapsulating the disperse system, wherein the acid group of the resin has been at least partly neutralized with an alkanolamine. The wall comprises the resin, and the resin may be crosslinked or cured with a crosslinking agent. Moreover, the process may comprise crosslinking or curing the resin constituting the wall with the crosslinking agent, and further crosslinking or curing the residual crosslinking agent with a polyfunctional compound. Such a process can produce a microcapsule has a small and uniform particle size while encapsulating a disperse system dispersed a colored particle in an oil phase.

Abstract: A paperboard laminate useful for making gable top juice cartons is provided. The laminate provides for a high melting point polymer such as a semi-crystalline nylon to be applied directly to a board surface as an oxygen barrier layer. An anti-scalping layer is also provided by a polar polymer which is connected by a tie layer to an outermost skin coat layer. Positioned between the skin coat layer and the oxygen barrier layer are one or more bulk layers of polyolefins. The resulting laminate affords a juice carton which has good oxygen barrier and Vitamin C retention properties, is resistant to overactivation during heat sealing, has minimal scalping of d-limonene and essential oils, and has excellent bulge resistance.

Also disclosed is a method for making the multilayer article.

Abstract: A method for producing a display capsule includes the following steps. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics is formed. A dispersing agent on an outer surface of the multichromal bead is applied, preferably via spray coating. The multichromal bead is then encapsulated. The invention is also directed to a method for producing multichromal capsules. A multichromal bead having at least two surfaces differing from each other in optical and electrical characteristics and further includes a charge control additive. A dispersing agent is applied on an outer surface of the multichromal bead to prevent diffusion of the charge control additive from the multichromal bead. The multichromal bead is encapsulated at an encapsulation reaction temperature greater than 40° C.

Abstract: A rubber composition includes ?,?-ethylenically unsaturated nitrile-conjugated diene copolymer rubber (A), ?,?-ethylenically unsaturated nitrile-conjugated diene copolymer rubber (B), ethylene-?-olefin copolymer rubber (C), and a graft copolymer (D). The graft copolymer (D) is obtained by performing graft copolymerization on a mixture of an aromatic vinyl compound and an ?,?-ethylenically unsaturated nitrite monomer with an ethylene-propylene-unconjugated copolymer.

A composition ratio of the rubber (A), rubber (B) and rubber (C) is rubber (A): 20 to 79 wt %, rubber (B): 1 to 30 wt %, and rubber (C): 20 to 50 wt %.

Abstract: The present invention relates to core-shell polymers having a hydrophilic copolymer shell, and a high level of core material of from 75 to 95 weight percent. The hydrophilic shell provides better coverage of the core resulting in better powder properties such as anti-blocking. The hydrophilic shell also allows for a thinner shell and a larger elastomeric core. Core-shell polymers of the invention are especially useful as impact modifiers for plastic materials.
