Abstract
Abstract Dialkenyl diacetylenes, especially divinyl diacetylenes having liquid crystalline phases, are provided. In accordance with certain preferred embodiments, diacetylenes having liquid crystalline phases are provided which may be polymerized while in the liquid crystalline state to yield conjugated polymers. The processes for the polymerization of such liquid crystalline diacetylenes and for the elaborati Portions of this work have been supported by the Defense Advanced Research Projects Agency, Grant No. DAAK-70-77-C-0045 (5-26502). The United States Government has certain rights in this invention.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
62 words
A method for preparing a polymerized article comprising providing a substrate, placing upon the substrate at least one layer of at least one composition comprising at least one divinyl or dialkenyl diacetylene monomer having a liquid crystalline state, causing said layer substantially to assume a liquid crystalline state, and imagewise polymerizing the layer while it is substantially in a liquid crystalline state.
Claim 2
Independent Claim
62 words
A method for preparing a polymerized article comprising providing a substrate, placing upon the substrate at least one layer of at least one composition comprising at least one divinyl or dialkenyl diacetylene monomer having a liquid crystalline state, causing said layer substantially to assume a liquid crystalline state, and imagewise polymerizing the layer while it is substantially in a liquid crystalline state.
Claim 3
Dependent Claim
23 words
The method of claim 1 further comprising applying an electric and/or magnetic field to the layer at least prior to said polymerizing step.
Claim 4
Dependent Claim
13 words
The method of claim 1 wherein said polymerization is initiated through actinic irradiation.
Claim 5
Dependent Claim
12 words
The method of claim 3 wherein said polymerization is initiated by heating.
Claim 6
Dependent Claim
14 words
The method of claim 1 wherein the layer is surmounted by a second substrate.
Claim 7
Dependent Claim
13 words
The method of claim 1 wherein said layer is substantially oriented inter se.
Claim 8
Dependent Claim
14 words
The method of claim 1 wherein said layer is bonded covalently to the substrate.
Claim 9
Dependent Claim
122 words
The method of claim 1 wherein at least one diacetylene has the formula: ##STR5## wherein R 1 and R 2 may be the same or different and are selected from the group consisting of H, cyano, halogen and alkyl having from 1 to about 3 carbon atoms; wherein R 3 and R 4 may be the same or different and are selected from the group consisting of H, cyano, halogen, amino, aryl and alkyl having from 1 to about 6 carbon atoms, and wherein R 5 and R 6 may be the same or different and are selected from the group consisting of H, cyano, alkyl, aryl, aralkyl, alkaryl and heterosubstituted alkyl and aryl having from 1 to about 30 carbon atoms.
