Abstract

PURPOSE:To obtain the titled novel polymer, having recurring units of a specific structure, capable of exhibiting a ferroelectric phase even at about ordinary temperature with a high speed of response to external factors and displaying moving pictures and useful also as display element for wide or bent screens. CONSTITUTION:The aimed polymer expressed by formula I {k and l are integers of 1-20; A is O or -COO-; m is 0 or 1; R<1> is formula II or III [Y is -COO- or -OCO-; R<2> is -COOR<3>, -R<3>, etc.; R<3> is formula IV (R<4> is CH3, Cl, etc.; n and p are 0 or integers of 1-10, provided that p is no 0 when R<4> is CH3; C* is asymmetric carbon atom)], etc.}. Furthermore, the above-mentioned polymer is obtained by alkylating, e.g. diethyl malonate with methylene dibromide, saponifying the resultant compound, reacting the obtained compound expressed by formula V with a hydroxy derivative, expressed by formula VII and available from a carboxylic acid expressed by formula VI to provide a dicarboxylic acid expressed by formula VII and polycondensing the resultant dicarboxylic acid with ethylene glycol, etc.
