C08F 446

US Classification:

526312

Abstract:

There is disclosed a new vinyl monomer capable of forming polymeric vesicles, micelles, monolayers, and side-chain liquid crystalline polymers. The vinyl monomer is of the formula ##STR1## wherein R. sub. 1 is substituted or unsubstituted long chain alkyl or aryl and R. sub. 2 is a hydrogen atom, alkyl, or aryl. The side-chain liquid crystalline polymers can be formed by free radical polymerization or by anionic polymerizations techniques. The different reaction methods give polymers of different configuration; the anionic technique results in a polymer having a nitrogen atom in the backbone. The polymers are useful in film and fiber formation and display good toughness.

Abstract:

There is disclosed a family of new vinyl monomers capable of forming polymers by free radical polymerization. The vinyl monomer is of the formula ##STR1## wherein R. sub. 1 and R. sub. 2 are substituted or unsubstituted hydrocarbons, X is O, NH or NR. sub. 3, and R. sub. 3 is substituted or unsubstituted hydrocarbon. The intermediates in the synthesis of these monomers are new beta-chloroalanine ureas. The polymers are useful in film and fiber formation and display good toughness. These new vinyl monomers also form a cyclic monomer.

International Classification:

C08F 2004

US Classification:

5263183

Abstract:

A process for synthesizing ethers of alkyl alpha-(hydroxymethyl)-acrylate by reacting alkyl acrylate and formaldehyde in the presence of a DABCO catalyst. The ethers may be used as cross-linking agents for thermoplastic polymers. Further, these ethers in turn enable synthesis of cyclopolymers that may show promising biological activity.

US Patent:

59051272, May 18, 1999

Filed:

Apr 8, 1997

Appl. No.:

8/825797

Inventors:

Robert Y Lochhead - Hattiesburg MS
Lon J Mathias - Hattiesburg MS

Assignee:

The University of Southern Mississippi - Hattiesburg MS

International Classification:

C07C57/02;57/18

US Classification:

526242

Abstract:

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.
