The goal of this study is to present the synthesis and characterization of a series of side-chain liquid crystalline polymers containing different number of oxyethylene units as spacer. The obtained polymers are characterized by DSC and polarizing optical microscope. Their phase behavior will be discussed as function of spacer length so as to understand the role of spacer on the properties of mesophases of side-chain liquid crystalline polymers. Experimental data indicate that the nature of spacer plays a very important role in a side-chain liquid crystalline polymer. The glass transition temperature of a side-chain liquid crystalline polymer decreases as number of oxyethylene unit of spacer increases. This means that the motion of a mesogen will be less affected by the polymer backbone when we put more oxyethylene units on the spacer.
