Cyclolinear polyorganosiloxanes POCS

During the last decade a new family of non-mesogenic mesophase polymers -cyclolinear polyorganosiloxanes (POCS) - consisting of linear chains of repeated siloxane cycles of various dimensions bonded either by only oxygen atoms or by flexible spacers was developed (1-5). The general formula of this class of polymers... [Pg.98]

The analysis of the effects of chemical structure both the siloxane backbone and the organic side groups of cyclolinear polyorganosiloxanes (POCS) on the phase transitions, the ability to form mesophase structures, the temperature range of mesophase existence and the structural evidence has been carried out.
