Abstract
Process for producing easily moldable composition of an acetylene high polymer by polymerizing acetylene using a catalyst system composed of (A) a transition metal compound containing at least one transition metal from Groups IVa, Va, VIa and VIII and (B) an organometallic compound containing at least one metal from Groups IIa, IIb, IIIb and IVb, the polymerization being carried out in a polymerization solvent containing the transition metal compound in a concentration of 0.0001 to 0.1 mole/liter to form a gel-like material consisting of an acetylene high polymer having a fibrous microcrystalline structure and the polymerization solvent.
Claims7
A process for producing a moldable composition of an acetylene high homopolymer, which comprises polymerizing acetylene using a catalyst system composed of (A) a transition metal compound of the formula Ti(OR).sub.4 wherein R represents alkyl having 4 carbon atoms, and (B) an organometallic compound of the formula AlR.sub.3 wherein R represents alkyl having up to 10 carbon atoms, wherein the catalyst system contains 1 to 25 moles of the organometallic compound per mole of the transition metal of the transition metal compound, and the polymerization is carried out under stirring in a polymerization solvent containing the transition metal compound in a concentration of 0.0001 to 0.1 mole/liter to form an acetylene high homopolymer having a fibrous microcrystalline structure which is swollen with the polymerization solvent.
