Abstract


A variety of new polymers ranging from soft to hard plastics were prepared by cationic polymerization of Adenopus breviflorus oil with styrene and divinyl benzene initiated by modified boron trifluoride etherate. The fully cured thermosets were found to contain between 78- 92% cross linked materials possessing crosslink densities of between 2.39 x 103 to 2.09 x 104 mol/m3 and glass transition temperatures of 12 – 800C. The tensile moduli of the materials ranged from 1.47 to 404MPa, the ultimate tensile stress varied from 0.18 to 7.78MPa and the elongation at break varied between 2 and 34%. Depending on composition, some of the materials possessed good damping and shape memory properties. Overall the newly prepared materials from Adenopus breviflorus oil hold a lot of promise as new polymeric materials.
