Abstract
An X-ray investigation has been made of a number of polymers with side mesogenic groups and different degrees of bonding of side groups and the main chain. Models of layered packing are proposed for the members of the series studied. It was found that with increase in the length of the spacer groups by more than 1·2 nm separate packing of the chains and side mesogenic groups takes place. The corresponding polymer is crystalline at room temperature. On melting this polymer the smectic B-phase forms. Rise in temperature leads to increase in the concentration and size of the regions of liquid crystalline orderliness in polymers with strong bonding of the main chains and side groups and worsening of the orderliness in the polymer with independent packing of the main chains and side groups.
