Patent number: 5905127Abstract: Mesogens are provided based on substituted unsaturated carboxylic acids such as acrylic and methacrylic acid. Substitution of a variety of hydrophobic tails onto the carboxylic acid or acid derivative via the vinyl carbon proximal to the carbonyl of the carboxylic acid results in mesogens that are capable of forming thermotropic and single-phase lyotropic mesophases over a broad range of compositions. The mesophases can be polymerized to lock in the ordered phases.Type: GrantFiled: April 8, 1997Date of Patent: May 18, 1999Assignee: The University of Southern MississippiInventors: Robert Y Lochhead, Lon J Mathias

Patent number: 5741847Abstract: A polymer polyol is produced by a process comprising free radical polymerizing an addition polymerizable di-(substituted phenyl)monomer (e.g., methacrylic ester of diglycidylether of tetrabromobisphenol A) component in the presence of a polyol, wherein the monomer has at least one aromatic halogen and at least one aromatic ethylenically unsaturated substituent. The polymer polyol can also be made by copolymerizing said monomer with an additional ethylenically unsaturated monomer component such as styrene and acrylonitrile. Said polymer polyols are reacted with a polyisocyanate compound forming a flame retardant polyurethane foam.Type: GrantFiled: May 23, 1996Date of Patent: April 21, 1998Assignee: The Dow Chemical CompanyInventors: Wayne R.
