## Abstract Summary: The vast majority of headβtoβtail stereoregular crystallizable polymers with an isotactic structure generally assume a helical symmetry in the crystalline state, compatible with the regular repetition along the chain axis of isomorphous isoclined units. There are at least two c
## Abstract For a polymer to be capable of forming a nematic, liquid crystalline state the molecules must be nearly rigid and rodβlike. There are two main classifications of such liquid crystalline states: lyotropic β generally applied to polymer solutions and implying the formation of a low viscos
