linear low density polyethylene (lldpe) was blended with esterified styrene-maleic anhydride (esma) and its physical and mechanical properties were studied. styrene-maleic anhydride (sma) copolymer was synthesized by precipitation reaction. then, sma was esterified by 1-decanol in methylethyl ketone solvent. from the ftir spectrum of esma it is evident that the corresponding peaks of anhydride ...

In the past few years, extensive improvements have been accomplished in reinforcing the structures through using shape memory alloys (SMAs). These materials absorb or dissipate energy through establishing a reversible hysteresis loop during a cyclic mechanical loading. This unique characteristic of the SMAs has made them appropriate for sensing, actuation, absorbing the impact energy, and vibra...

Chelating resins have been considered to be suitable materials for the recovery of heavy metals in water treatments. A chelating resin based on modified poly(styrene-alt-maleic anhydride) with Melamine was synthesized. This modified resin was further reacted with 1,2-diaminoethan in the presence of ultrasonic irradiation for the preparation of a tridimensional chelating resin on the nanoscale f...
