An oxygen scavenging polyolefin composition and methods of making thereof are described herein. In one approach, the composition includes a continuous non-polar polyolefin matrix having oxygen scavenging domains dispersed therein. The oxygen scavenging domains include an oxidizable polymer, a transition metal catalyst or salt thereof, and a catalytic promoter effective to bind with oxygen passing through the continuous non-polar polyolefin matrix. The oxygen scavenging domains forming a discrete polar region within the continuous non-polar polyolefin matrix. The composition further includes a polymeric compatibilizer having a polar moiety and a non-polar moiety and in amounts effective to uniformly disperse the polar oxygen scavenging domains in the continuous non-polar polyolefin matrix.

Oxygen scavenger system in a polyolefin matrix

A suspended ceiling grid tee of conventional cross-sectional shape having a plurality of generally planar parallel and orthogonal surfaces and at least two electrically isolated conductor strips attached to the planar areas of the tee surfaces extending along substantially the full length of the tee, a connector for supplying low voltage electrical power to or from the conductors, the connector having a configuration complementary to the cross-sectional shape of the grid tee and including at least two electrical contacts for energizing each of said conductor strips when said connector is positioned on said grid tee.

Electrified suspended ceiling grid

A rectangular ceiling tile proportioned for use in a standard rectangular ceiling grid module formed by grid tees, the tile having a pair of conductors arranged to feed low voltage electrical power from the grid elements to an electric or electronic device carried on the tile, the conductors each extending to an edge or edges of the tile and adapted to make physical contact with a conductor carried on a grid element when supported on such grid element.

Specialty ceiling structure and functional ceiling grid

An elongated grid tee for supplying low voltage power on a suspended ceiling comprising at least two electrically conductive paths electrically insulated from each other, extending lengthwise of the tee, and accessible for receiving or supplying electrical power at numerous locations along the length of the tee.
