Abstract

Disclosed are saturated cyclic monopolymers derived from hexyne, octyne, nonyne, pentadecyne and saturated cyclic copolymers derived from acetylene and a second alkyne monomer that is hexyne, octyne, nonyne, or pentadecyne.

First claim

What is claimed is:

1. A composition comprising a saturated cyclic copolymer comprising a hydrogenated copolymer comprising randomly dispersed acetylene and a second alkyne monomer, said monomer selected from group consisting of 1-octyne and 1-nonyne, and said saturated cyclic copolymer having a structural formula:

wherein:
R is n-hexyl, or n-heptyl;
when R is n-hexyl, a molar ratio of incorporated acetylene to incorporated second alkyne monomer is from 34 to 59:41 to 66;
when R is n-heptyl, a molar ratio of incorporated acetylene to incorporated second alkyne monomer is from 15 to 43:57 to 85;
n is an integer greater than or equal to 1; and
m is an integer greater than or equal to 1.

2. A composition comprising a saturated cyclic copolymer comprising a hydrogenated copolymer comprising randomly dispersed acetylene and a second alkyne monomer, and said saturated cyclic copolymer having a structural formula:

Wherein: R is n-tetradecyl; a molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 15:85;
n is an integer greater than or equal to 1; and
m is an integer greater than or equal to 1.

3. The composition of claim 1 , wherein R is hexyl, and a comonomer molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 59:41.

4. The composition of claim 1 , wherein R is hexyl, and a comonomer molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 47:53.

5. The composition of claim 1 , wherein R is hexyl, and a comonomer molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 34:66.

6. The composition of claim 1 , wherein R is heptyl, and a comonomer molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 43:57.

7. The composition of claim 1 , wherein R is heptyl, and a comonomer molar ratio of incorporated acetylene to incorporated second alkyne monomer is about 15:85.

8. The composition of claim 1 , wherein a relative purity of the saturated cyclic copolymer determined by a nuclear magnetic resonance spectroscopy (NMR) analysis is about 75% to about 99%.
