Four adhesives (one adhesive BEA 811 and three adhesives BENDA 811) containing new bismaleimide (BMI: B 8 and B 11) with aramide/arylate and polymethylene as mesogen and flexible groups, respectively were studied. Starting from the BMIs, eutectic mix
Synthesis and Dielectric Study of New Liquid-crystalline Polysiloxanes Presenting a Thioether Spacer
Publikováno v:
Macromolecular Chemistry and Physics. 204:2222-2232
Three new cyanobiphenyl polysiloxanes presenting long thiother spacers have been carried out. This type of spacer leads to very stable liquid-crystalline polymers at room temperature and remove the crystallinity phenomenon. Dielectric analysis result
