Novel Polymeric Liquid Crystals And Methods For Their Preparation

View page
US Patent:
4617371, Oct 14, 1986
Filed:
Nov 29, 1982
Appl. No.:
6/445081
Inventors:
Alexandre Blumstein - Chelmsford MA
Jawed Asrar - Lowell MA
International Classification:
C09K 1952
G02F 113
C08G 6316
US Classification:
528194
Abstract:
Polymeric liquid crystals which retain their mesomorphic structure and properties associated therewith at temperatures below their glass transition temperature are described. The polymers contain mesogene and spacer units in alternating sequence in the main chain and may carry aliphatic substituents.

Substituted Extensively Conjugated Ionic Polyacetylenes

US Patent:
5037916, Aug 6, 1991
Filed:
Mar 16, 1990
Appl. No.:
7/494573
Inventors:
Alexandre Blumstein - Chelmsford MA
Sundar Subramanyam - Stoneham MA
Assignee:
University of Lowell - Lowell MA
International Classification:
C80F13802
US Classification:
526240
Abstract:
A family of ionic polyacetylenes containing long sequences of conjugated double bonds in the backbone with ionic charges adjacent to or in conjugation with the backbone, and a synthetic process for preparing them, are disclosed. These polymers, which are soluble in many solvents, including water, are mono- and di-substituted polyacetylenes that are extensively conjugated. The charge density and geometry of charge distribution depends on the number and nature of the substituents.
