Maleic anhydride grafted polypropylene (MA-g-PP) is an excellent choice because the anhydride functionality of MA-g-PP reacts with cellulosic fiber hydroxyl groups and esterification gives stronger links between the fiber surface and the PP matrix [6] Reducing the PP molecular weight lowers the viscosity of the molten polymer reduces the shear stress between individual fibers and between maleic anhydride (MA) DCP from Merck and Irganox B225 from Ciba Co were used B Processing First Step: Grafted PP with overall contents of 0 1 2 3 and 4 phr of maleic anhydride and 0 1 phr of DCP and 0 01phr Irganox B225 were performed by melt mixing in an optimum condition for processing in Haake Rheometer 90 were

Composites of polypropylene/Candelilla fiber (Euphorbia

maleic anhydride with a loss of hydrogen chloride to give products that yield upon hydrolysis a mixture of acids The former adds both one and two moles In general only acyclic dienes containing a single halogen (C=CC1--C=C) add dienophiles as readily as do the of maleic anhydride in the 3-position l parent hydrocarbons The highly reactive hexachloropentadiene adds maleic anhydride

Maleic anhydride-modified polypropylene (MAPP) is a compatibilizer used to improve the physical and mechanical properties of many wood/plastic composites (WPCs) The properties of WPCs containing MAPP differ according to the characteristics of the specific MAPP that it is used In this study the physical and mechanical properties including shear viscosity of polypropylene-based WPCs

The use of cellulose as a separator was a forward step which made the Ag-Zn sec-ondary battery practical (ref 1 p 263) Unfortunately cellulose films suffered sig- nificant degradation as a result of reaction with battery constituents Polyvinyl alcohol films were also attacked by alkaline silver oxide but not as extensively as cellulose (ref 2) Three other types of polymeric membrane
