SYNTHESIS,CHARACTERIZATION AND OPTICAL PROPERTIES OF THE COPOLYMERS OF C_(60) AND 1-PHENYL-1-PROPYNE*

Received Date: 13 December 1998

While WCl6-Ph4Sn fails to polymerize 1-phenyl-1-propyne (PP) at room temperature, highmolecular weight (Mw up to 410× 103) polymers are obtained in high yields (up to 80%) when thepolymerizations of PP are carried out in the presence of C60 using the W catalyst under the same conditions.The polymers are soluble in common organic solvents such as THF, chloroform, and toluene. Molecularstructures of the polymers are characterized by FT-IR, UV, NMR, GPC and XRD, and it is found that C60 is copolymerized with PP.Thus C60 plays the dual roles of comonomer and cocatalyst in the porymerization reaction.C60 contents of the copolymers can be easily changed by varying the C60 amounts in the feed mixtures.The copolymers effectively limit strong 532 nm laser pulses,whose limiting performance is superior to that of parent C60.
