Extract

The effect of silica nano-particle filler on poly(ethylene-co-hexene)/xylene gels has been investigated using mainly small angle neutron scattering and rheological measurements. Both non-filled and filled polymer gels show same characteristics in the structure factor and mechanical properties during melting and gelation. These observations suggest that particle interaction is screened by the absorbed polymers and the effect of the silica filler is mainly softening the gelation transition by introducing defects to the crosslinking microcrystals.
