Abstract
Abstract ABSTRACT OF THE DISCLOSURE Diacetylenes of the formula R1-(CH2)8-C?C-C?C- (CH2)8-R2 where R1 and R2 ar? hydrogen or hydrocarbon ra?icals, R1 and R2 being the same or different, are disclosed. A process for the manufacture of the diacetylenes is also disclosed. The diacetylenes may be polymerized to give in particular conjugated polymers. A process for polymerizing the polymers and the polymers so obtained are disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
55 words
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A polymer consisting essentially of the polymeriza- tion product of one or more diacetylenes of the formula: R1 (CH2)8-C?C-C?C-(CH2)8-R2 where R1 and R2 are hydrogen or hydrocarbon radicals, R1 and R2 being the same or different.
Claim 2
Dependent Claim
13 words
The polymer of Claim 1 in which the polymer is a conjugated polymer.
Claim 3
Dependent Claim
15 words
The polymer of Claim 2 in which R1 and R2 are hydrogen or alkyl radicals.
Claim 4
Dependent Claim
14 words
The polymer of Claim 3 in which all the diacety- lenes are the same.
Claim 5
Dependent Claim
22 words
The polymer of Claim 3 in which R1 and R2 are hydrogen or linear alkyl groups of 1 to 8 carbon atoms.
Claim 6
Dependent Claim
21 words
The polymer of any one of Claim 2, Claim 3 and Claim 4 in which R1 and R2 are the same.
Claim 7
Dependent Claim
48 words
A process for the polymerization of one or more diacetylenes of the formula: R1(CH2)8-C?C-C?C-(CH2)8-R2 where R1 and R2 are hydrogen or hydrocarbon radicals, R1 and R2 being the same or different, comprising the steps of crys- tallizing said diacetylenes, polymerizing the diacetylenes and separating the polymer so formed.
Claim 8
Dependent Claim
14 words
The process of Claim 7 in which the diacetylenes are polymerized using photoinitiation techniques.
Claim 9
Dependent Claim
25 words
The process of Claim 8 in which the photoinitiation uses electromagnetic radiations of wavelengths in, or less than, the visible range of the electromagnetic spectrum.
Claim 10
Dependent Claim
15 words
The process of Claim 9 in which R1 and R2 are hydrogen or alkyl radicals.
Claim 11
Dependent Claim
14 words
The process of Claim 10 in which all the diacetyl- enes are the same.
Claim 12
Dependent Claim
22 words
The process of Claim 11 in which R1 and R2 are hydrogen or linear alkyl radicals of 1 to 8 carbon atoms.
Claim 13
Dependent Claim
22 words
The process of any one of Claim 9, Claim 11 and Claim 12 in which R1 and R2 are the same. 11
