Thermotropic polyesters: modelling of the meridional diffraction patterns of poly( p-oxybenzoate- co- p-phenylene isophthalate) fibres
Previous work has shown that poly( p-oxybenzoate- co- p-phenylene isophthalate) ( 50 50 and 67 33 ) fibres spun from nematic mesophase are highly oriented but lack crystalline order. Heat treatment of these ‘as-made’ fibres results in structure regarded as a mosaic of thin crystalline regions consis...

p-oxybenzoate-
co-
p-phenylene isophthalate) (
50
50
and
67
33
) fibres spun from nematic mesophase are highly oriented but lack crystalline order. Heat treatment of these ‘as-made’ fibres results in structure regarded as a mosaic of thin crystalline regions consisting of
p-phenylene isophthalate sequences in a paracrystalline matrix. This work is concerned with atomic modelling of the copolymer chains. One-dimensional Fourier transforms generated from the models are compared with the observed meridional diffraction traces of the ‘as-made’ fibres. A good match is obtained for the extended chain models containing ‘
trans’ conformations of
p-oxybenzoate and
p-phenylene dioxy units. |
