Extract

Several research projects in our laboratory have used an LCP based on 4,4'-dihydroxy,a-a' dimethylbenzalazine, that was first synthesized by Roviello and Sirigu 1.2 Copolymers with the following qeneral structure,

have been used in self-reinforcing polymer blends3 and are currently being used in small angle neutron scattering studies of the molecular conformation of an LCP in a nematic field. In this latter study, it is imperative that the polymer be well characterized, especially with respect to molar mass and thermal stability. This paper describes the effect of molar mass and thermal history on the thermal stability and transitions of this particular LCP.
