| titleOfInvention | Polyethylacetylene derivative and process for preparation thereof |
| abstract | A novel polyethynylacetylene derivative represented by the formula ##STR1## wherein R is H, (C1-7) alkyl, phenyl, benzyl, naphthyl, carbazole, (C2-7) vinyl-alkyl --CX 1 X 2 (OH) or --SiX 1 X 2 X 3 in which X 1 , X 2 and X 3 are H, (C1-7) alkyl, phenyl or benzyl, with the proviso that the case where all of X 1 , X 2 and X 3 are H is excluded and x is a number of 20 to 500. The polyethynylacetylene derivative is prepared by polymerizing a monomer of the formula HC.tbd.C--C.tbd.CR wherein R is as defined above, with the proviso that the case where R is H is excluded, in the presence of a metathesis catalyst or a Ziegler catalyst. A polyethynylacetylene derivative of the above formula (wherein R=H) is prepared by reacting a polyethynylacetylene derivative of the above formula wherein R=Si(C n H 2n+1 ) 3 with a desilylating agent. The polyethynylacetylene derivative is soluble in organic solvents and can be shaped into various articles. This polymer is used as a high-sensitivity pattern-forming material and is promising as a precursor for polyacene polymers. |
