| dc.description.abstract | A series (15:85%) translucent intact IPNs made of a reactive rubber (Jeffamine™), a commercially available epoxy and unsaturated polyester were prepared. All IPNs showed increased toughness with incorporation of the Jeffoxy rubber. DMTA data showed a single Tg phenomena and narrow peak widths with a shift in Tg for all rubber containing IPNs. Jeffoxy DMTA data showed high molecular weight tri-amine T-5000 with highest tan~ value (2xT-403). DSC calculations showed complete extent of cure at 90°C for an Sh cure time. A 45% xi increase in Izod impact strength (toughness) with least standard deviation recorded for T-509 containing IPN. T-509 strength was comparable to that of the pure PE. Stiffuess and strength values documented for all IPNs using a three-point. bend flexural test. Material with the highest flexural modulus was that of linear diamine D-2000. Highest strength recorded for T-403 and D-2000 IPNs. SEM images showed T-509 with no scattered particles (l-20µm) suggesting good distribution of rubber particles in polyester. TGA values compared well with that of the neat polyester the exception was that ofT-403 which exhibited a 20°C decrease. | |
