ABSTRACT:
A side chain liquid crystal polymer and a manufacturing method therefor are provided. Also, an optical recording medium of which recording layer is made of the side chain liquid crystal of the present invention is provided. The side chain liquid crystal polymer expressed by the following formula (V) has excellent processing properties due to its high solubility. Also, due to its high glass transition temperature and low polydispersity, information recorded on a recording layer made of the polymer can be preserved for a long time. In addition, since the recorded type (pit) is even, the error rate is low and the occurrence of jitter noise can be remarkably reduced: ##STR1## where A is either CH.sub.2 or CH.sub.2 --O--(CH.sub.2).sub.m, R is either OCH.sub.3, CN or NO.sub.2, l is 10 to 100, m is 1 to 6, and n is to 20.
