Abstract Cysteamine functionalised reduced graphene oxide (rGO) was grafted to polypropylene-graft-maleic anhydride (PP-g-MA) and subsequently melt blended with PP. The covalent bridging of rGO PP-g-MA via the cysteamine molecule co-crystallization are routes promoting interfacial interactions between PP matrix. A rheological percolation threshold achieved for a nanofiller loading 3 wt% 5 wt%, ...

The objective of this study was to develop a stable intravenous solution of 1-mg/mL morphine sulfate in polypropylene bags for use in patient-controlled analgesia pumps for postoperative pain management. Three large-scale batches of 1-mg/mL morphine sulfate solution filled into polypropylene bags and terminally sterilized at 120 deg C for 20 minutes were used in this study. The stability of the...

We report the design, synthesis, morphology, phase behavior, and mechanical properties of semicrystalline, polyolefin-based block copolymers. By using living, stereoselective insertion polymerization catalysts, syndiotactic polypropylene-block-poly(ethylene-co-propylene)-block-syndiotactic polypropylene and isotactic polypropylene-block-regioirregular polypropylene-block-isotactic polypropylene...
