Handbook of Clinical Child Neuropsychologyonds. The different methods of measuring orientation parameters for liquid crystal polymer samples are compared. Particular emphasis is placed upon X-ray and electron scattering procedures which are able to provide structural as well as orientational information. The experimental methods are highlighted through the use of several examples.

Biologically Produced (,)-3-Hydroxy- Alkanoate Polymers and Copolymers, in the 3-position. The most common homopolymer is poly (3-hydroxybutyrate), PHB, which has a 3-methyl substituent, but monomers having C.-C. alkyl side groups are found in natural copolyesters. The monomers are all optically active in the r absolute configuration. Phb can be produced from carbon su

Orientation in Liquid Crystal Polymers,eme of the liquid crystal state; however, its definition requires considerable care. The basic mathematical relationships for the description of molecular anisotropy are reviewed together with an assessment of the various ‘orienting’ units ranging from the molecular envelope to particular covalent b

Application of High-Resolution 13C NMR To Crystalline Polymers,loses are reviewed. Characteristic .C spectra, determined by three principal values of the chemical shift tensor, are obtainable by applying a sufficiently large resonant oscillating magnetic field to .H nuclei (DD). The determination of the principal axes of the chemical shift tensor of orthorhombi
