   Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

3. 2. Study of ethylene/propylene polymerization, using a 4th generation Ziegler-Natta catalyst: Effect of external donor and feed ratio on polymerization

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Seyedeh Shafagh Dehghani; [2012]
   Keywords : Ziegler-Natta catalysts; Electron Donor; Copolymerization; Polyolefins;

   Abstract : A fourth generation multiple site Ziegler-Natta catalyst was used to synthesize ethylene and propylene homo-and copolymers in the presence of hydrogen. This type of catalysts produce polymers with broader molecular weight distribution (MWD), chemical composition distribution (CCD) and stereoregularity than other coordination polymerization catalysts since it has more than one active site.
