dc.description.abstract | The structure and properties have been comprehensively studied for metallocene copolymers
of propylene-1-hexene (CiPH) and propylene-1-octadecene (CiPOD). The comonomer content
constitutes the most important factor affecting both structure and properties in these CiPH
and CiPOD copolymers, although the length of the
comonomer is also very important. Thus, a considerable
decrease in crystallinity and an easier obtainment
of mesomorphic-like ordered entities are observed in
the two kinds of copolymers as comonomer content
increases. The variations in crystalline structure significantly
influence the viscoelastic and mechanical
behaviors of these CiPH and CiPOD copolymers. Consequently,
the location and intensity of the different
relaxation mechanisms as well as stiffness parameters
(storage, Young’s moduli, and microhardness) and
deformation mechanism are strongly dependent upon
composition. | |
