The catalytic system formed from polymer-supported neodymium complexes shows high catalytic activity and stereospecificity for butadiene polymerization.
The results showed that with the increase of contents of oxygen,rust and peroxid seed in the recovery system,the formation of butadiene peroxid and its self-polymer increased rapidly.
It's unlikely to be the plastic itself: LEGO typically uses acrylonitrile butadiene styrene, or ABS, plastic—a highly durable polymer that keeps the pieces strong for building, or what LEGO calls " clutch power."
