Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 7517-19-3, Name is H-Leu-OMe.HCl, molecular formula is C7H16ClNO2, belongs to amides-buliding-blocks compound. In a document, author is Saxena, Sonashree, introduce the new discover, COA of Formula: C7H16ClNO2.
Microparticles as Additives for Increasing the Mechanical Stiffness of Polypropylene
Composite materials of polypropylene and mineral microparticles have been generated by compounding and tested in terms of mechanical stiffness. In a first step silica, boehmite and functionalized clay microparticle powder have been mixed with the polymer in a twin-screw compounder. The elastic modulus was highest for mixtures with a microparticle concentration of 5 to 10%w/w. An increase of 25% of the elastic modulus was achieved by simple melt extrusion. In a second step, a maleic anhydride-grafted polypropylene (PP-g-MA) was used as a matrix. When measured by nanoindentation, the pure PP-g-MA matrix showed an elastic modulus twice as high as pure PP, probably because of a partial reticulation. During extrusion, amino-silane functionalized clay microparticles were added to the PP-g-MA matrix and reacted with it by budding covalent amide group bonds. The resulting compound material showed an elastic modulus of more than four times the stiffness of pure PP.
