Patent number: 7368483Abstract: A low-k organic dielectric material having stable nano-sized porous is provided as well as a method of fabricating the same. The porous low-k organic dielectric material is made from a composition of matter having a vitrification temperature (Tv-comp) which includes a b-staged thermosetting resin having a vitrification temperate (Tv-resin), a pore generating material, and a reactive additive. The reactive additive lowers Tv-comp below Tv-resin.Type: GrantFiled: April 19, 2004Date of Patent: May 6, 2008Assignees: International Business Machines Corporation, Dow Global Technologies, Inc.Inventors: Eric Connor, James P. Godschalx, Craig J. Hawker, James L. Hedrick, Victor Yee-Way Lee, Teddie P. Magbitang, Robert D. Miller, Q. Jason Niu, Willi Volksen

Patent number: 7312253Abstract: A blowing agent blend for making thermoplastic polymer foams comprises methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend can comprise any combination of methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce stable foams for various applications, including containers, packaging systems, as well as insulation boards and building materials. A process for the preparation of such foams is also provided.Type: GrantFiled: December 17, 2004Date of Patent: December 25, 2007Assignee: Pactiv CorporationInventors: Yash Paul Handa, Joseph A. Brackman, Glenn C. Castner, Mohammad Zafar
