TL;DR: In this article, the tensile stress and strain of AAm-grafted rubber powder/compatibilizer/HDPE composites always exhibit higher values than those of unmodified rubber powder-filled composites.
Abstract: Mechanical and dynamic mechanical properties of a waste rubber powder-filled high-density polyethylene (HDPE) composite are investigated. Rubber powder is surface-modified with acrylamide (AAm) using ultraviolet. Rubber powder and HDPE are extruded using a single-screw extruder and maleic anhydride-grafted polypropylene is added as a compatibilizer to improve the adhesion between rubber powder and HDPE. The tensile stress and strain of AAm-grafted rubber powder/compatibilizer/HDPE composites always exhibit higher values than those of unmodified rubber powder/HDPE composites. Surface modification of rubber powder is shown to decrease the magnitude of the tan δ of the HDPE composite. Higher values of the notched Izod impact strength of a surface-modified rubber-filled composite is observed compared to those of unmodified rubber-filled composite. Experimental results show that acryl amide-grafted rubber powder reacts with maleic anhydride and it results in improved mechanical properties of the HDPE composite. © 2000 John Wiley & Sons, Inc.

TL;DR: The stress transfer between PVA and ChWs interface, and higher PVA crystallinity induced by ChWs were reflected to the outstanding enhancement in mechanical- and anti-creep properties of nanocomposite fibers.

TL;DR: The glass-rubber transition temperatures (Tg) of several cellulosic polymers, including HPMC, hydroxypropyl methylcellulose, HPC, and HEC have been examined using dynamic mechanical analysis (DMA).

TL;DR: The elastic modulus was more sensitive to moisture than viscous modulus and loss tangent but all three properties showed no overall consistent trend in the results following the storage periods, thus giving a greater insight into material behavior.
