Graft polymerization of acrylic acid onto nonwoven polypropylene (PP) fabric was carried out by a preirradiation method using a Co gamma radiation source. Results showed that 2.2'-Azobisisobutyronitrile (AIBN), its concentration was 0.2%, was very important during the grafting polymerization without removal of polymerization inhibitor of AA. The most favorable grafting polymerization conditions...

Abstract Siombak Lake is an artificial lake in Medan City. We investigated microplastic pollution tropical tidal waters the current research. Grab samples of water and sediments were taken by Indonesian standards. Organic digestion density separation used preparation sample. The categorization polymer was determined Raman Spectrophotometry, quantity shape, microscopy. result indicated that sedi...

Recently, there has been increasing interest in studying microplastic pollution because of its dangerous effects on human health through the food chain. This paper presents first results obtained density some marine species (including oysters, green mussels, mullet and tonguefish) cultured Ba Ria – Vung Tau Province. The indicated that microplastics were present 100% analyzed samples with diffe...

Core–shell polybutadiene-graft-polystyrene (PB-g-PS) graft copolymers with different ratios of PB to PS are synthesized by emulsion polymerization. Further, the PB-g-PS blended polypheylene ether (PPE) and prepare PPE/PS/PB-g-PS blends. The effects copolymer structure matrix composition on morphological, mechanical properties, deformation mechanism blends studied. results show that submicromete...

Poly N-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. In this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 KGy) under appropriate temperature and grafting conditions was investigated. The FTIR analysis showed the existence of the graft PNIPAAm on the substrate. The optimal value of the dose for grafting was ...
