Poly(L-lactic acid)/deproteinized natural rubber blends with enhanced compatibility

نویسندگان

چکیده

PLLA-g-LMWNR (LMWNR – low molecular weight natural rubber) was used as a compatibilizer (1–3 wt %) of poly(L-lactic acid)/deproteinized rubber (PLLA/DPNR) blend (95/5 w/w). The LMWNR prepared using TiO2/ZnO (9 : 1 w/w) and H2O2 co-catalyst. obtained grafted with 0–12 % maleic anhydride (LMWNR-g-MA) then PLLA (PLLA-g-LMWNR). A significant improvement in the mechanical properties PLLA/DPNR found that contained 3 PLLA-g-LMWNR. Scanning electron microscopy showed decrease pore diameter from 5.44 to 1.56 μm. thermal analysis blends Tg value phase shifted 63.1 61.4°C. These results confirmed can enhance compatibility blend.

The Cyclization of Natural Rubber

The effects of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber (NR) was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl4). Iodometric titration show, with 8% SnCl4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of c...

Production and characterization of natural rubber-Ca/P blends for biomedical purposes.

This study presents the development of natural rubber-Ca/P blends, as promising candidates for biomedical purposes. The specific objective was the incorporation of Ca/P into a natural rubber polymeric matrix. Ca/P crystalline phases were synthesized by the sol-gel method and the polymeric matrices were produced using natural rubber extracted from latex of the Hevea brasiliensis. The shape and s...

Flow behaviour of polyvinyl alcohol (PVOH) modified blends of polyvinyl acetate (PVAc)/natural rubber (NR) latexes

During compounding processes, polymer latexes are mixed with various colloidal systems (in particular, PVOH) or surface-active agents to modify the flow behaviour in order to suit the manufacturing process. In this study, the flow behaviour of aqueous dispersed PVAc, NR and different mixed dispersions were investigated both in the absence and presence of PVOH as flow modifier, using an Ostwald ...

Natural rubber latex allergy.

Immediate hypersensitivity to natural rubber latex (NRL) has become increasingly common during the last 20 years. It is currently one of the most frequently encountered occupational diseases among the healthcare workers and a problem even in other occupations where protective gloves are used. Several groups at high risk for developing NRL allergy have been defined, including healthcare workers ...
