New catalyst makes PP stiffer, more processable. (In Brief).Basell in Wilmington, Del., has a new Ziegler-Natta catalyst A Ziegler-Natta catalyst is a reagent or a mixture of reagents used in the production of polymers of 1-alkenes (α-olefins). Ziegler-Natta catalysts are typically based on titanium compounds and organometallic aluminium compounds, for example triethylaluminium, (C2 family that is said to significantly expand the properties of polypropylene polypropylene (pŏl'ēprō`pəlēn), plastic noted for its light weight, being less dense than water; it is a polymer of propylene. It resists moisture, oils, and solvents. homopolymers and impact copolymers by broadening their molecular-weight distribution. These succinate succinate /suc·ci·nate/ (suk´si-nat) any salt or ester of succinic acid. succinate semialdehyde ?. suc·ci·nate n. catalysts were recently tested in commercial PP plants in Italy and the Netherlands. Basell expects to use them commercially early next year. "We have produced heterophasic copolymers with unprecedented stiffness/impact balances," says Michael Mulrooney, V.P. of Basell's catalyst business. Succinate catalysts are expected to improve stiffness and processability of BOPP film, pipe, and injection molded mold 1 n. 1. A hollow form or matrix for shaping a fluid or plastic substance. 2.
