The synthesis and phase behaviour are described of new side-chain liquid crystal polyacrylates (9a-9d) with a 3,5-isoxazoline ring in their mesogenic core. The new homopolymers were synthesised by free radical polymerisation. Phase transition temperatures exhibited dependence on degree of polymerisation and on terminal groups. The resulting materials exhibited typical smectic A mesomorphism.
