This paper presents a synthetic pathway leading to a new class of materials--crosslinked acrylic-polydiethylsiloxane copolymers. They combine the mesomorphic properties of long alkyl-substituted siloxanes with well defined acrylic/siloxane networks. In order to obtain telechelic bis(3-aminopropyl)-oligodietythylsiloxanes, the equilibration reaction of nexaethylcylotrisiloxane with bis(3-aminopropyl)-tetramethyldisiloxane has been studied. The next synthetic step of the synthesis involved the addition of amino terminated oligosiloxanes to vinyl isocyannates leading to UV-crosslinkable vinyl macromonomers. Several crosslinking reactions of the vinyl terminated oligosiloxanes in acrylic matrix have been carried out. Variable proportions of siloxane and acrylate components led to the mesomorphic elastomers with different mechanical properties.
