Abstract: Improved solventless processing technology for additive blends containing a polymer carrier, including those which have high level of additives, is described. High concentrations of low-melting, sticky additives lead to phase separation and extrusion instability, such that pellets cannot be formed from such additive blends by traditional extrusion process. These blends include those with a high level of active additives that have been described in the literature as Type A Superblends. Here a polymer typically acts as the carrier of the additives. The new and improved technology involves the solid state compaction processing, using a tubular die, of such impossible-to-pelletize additive blends of the Type A composition to produce commercially useful pelletized additive blends.

Abstract: A masterbatch of additives is useful for maintaining a constant and reduced coefficient of friction in polyethylene (PE) based films. The masterbatch is a compounded blend of siloxane additive in conjunction with a mineral, a cyclic olefin copolymer and, optionally, an antioxidant. These additives are different from the polar additives used in the past to reduce COF of PE films and do not have inherent incompatibility with the nonpolar PE matrix.
Abstract: A lens component 10 comprises K unit lenses 11, each extending in the X direction and having a common structure, arranged in parallel at a minimum period PL in the Y direction. Each unit lens 11 includes two partial lenses 121, 122 sectioned within the minimum period PL in the Y direction and a flat part 13 disposed between the partial lenses 121, 122. The partial lenses 121, 122 have respective optical axes different from each other but parallel to the Z direction and form images of a common point on an object surface onto an image surface A at respective positions different from each other.

Abstract: The present invention is directed to a deep draw microcellularly foamed polymeric container comprising a polymeric sidewall integrally connected to a polymeric base along a bottom edge. The polymeric sidewall and base are contiguous with each other and define a shape of an open top container. The polymeric sidewall and base have a contiguous inner microcellular foam structure (having average cell diameters ranging from about 5 to about 100 microns) surrounded by a smooth outer skin layer integrally connected therewith. The polymeric sidewall defines a container height and a top opening, wherein the top opening defines a top opening width, and wherein the polymeric base defines a container base width, and wherein the area defined by the top opening is greater than the area defined by the polymeric base, and wherein the ratio of the container height (h) to the top opening width (w) is greater than about 1:1 (h:w).
