Side-chain liquid crystalline polymers (SCLCPs) with differing spacer groups have been prepared as copolymers or as blends of the individual homopolymers. The resulting materials have been examined by thermal and optical methods. The copolymers showed intermediate properties between those of the homopolymers. In contrast, blends of SCLCPs with either chemically distinct or similar side-chain spacer units showed two clearing points (both of which are lower than those of each homopolymer) and one major melting point. We interpret the latter results in terms of partial contamination of each phase by a small amount of the other phase.
