| Abstract: | The polymerization of long chain derivatives of sorbic and muconic acid was studied in the solid state. Crystals of sorbic acid n-octadecylester (1), sorbic acid n-octadecylamide (2), and 6-n-octadecanoylamino sorbic acid (3) were found to rapidly polymerize upon UV- or -irradiation. A 1,4-trans-polymer was obtained in a high yield. Crystals of muconic acid di-n-octadecylester (4) and muconic acid di-n-octadecylamide (5) were completely photoinactive.Polymerization of3 was also investigated in monomolecular layers at the air-water interface and in Langmuir-blodgett type multilayers. The polymer formed upon UV- irradiation of mono- and multilayers was identified by infrared spectroscopy as the 1,4-trans-adduct. |
