Abstract
Thin films of bis-(-p-toluene sulphonate) of 2,4-hexadiyne-1,6-diol monomer (TS) and its polymer, PTS, are successfully prepared by the classic Langmuir-Blodgett techniques. X-ray diffraction reveals highly ordered structures in the films. The three diffracted peaks observed in the range of 2θ=5° to 25° coincide well with those of the (010) plane in TS single crystal. A trial has been made to prepare a mixed film of TS and arachidic acid, but complete phase separation occurs and TS molecules preferentially tend to form films. Comparison between thed-values of TS and PTS film confirms that the polymerization in the TS thin films is also solidstate topochemical polymerization.
