Abstract
Some preliminary results on the new unsymmetrical diacetylene pTS-pFBS are presented. pTS-pFBS is the disubstituted molecule R‒C˭C‒C˭C‒R’ where R is CH3-Ph-SO3-CH3O and R’ is F-Ph-SO2-CH2O, R and R’ being respectively the side groups of the well known symmetrical diacetylenes pTS and pFBS. Synthesis, crystallization and thermal polymerization data are described. The X-ray crystal structures of monomer and polymer pTS-pFBS had been determined at 143 K and are discussed in terms of particular reflections.
