A series of side chain liquid crystal polyurethanes (CnCNPs), in which the spacer length was varied from 2 to 12 methylene units, were synthesized by the addition polymerization of ␣-[bis(2-hydroxyethyl)amino]--(4-cyanoazobenzene-4Ј-oxy)alkanes (CnCN-diols) with hexamethylene diisocyanate.

## Abstract The structure of poly(L‐lysine) containing 44% azobenzene units in the side chain was studied by X‐ray diffraction between room temperature and 150°C. The polymer exhibits a mesomorphic structure of the smectic A1 type. In this structure, stable at least until 150°C, each smectic layer
