One process, called ring-opening metathesis polymerization, opens carbon rings and elongates them into chains. The other process, called cross metathesis, inserts chains of polymer subunits from ...

In 2005, the prize went to developers of the metathesis reaction, which breaks and makes double bonds between carbon ... A ruthenium catalyst facilitated the polymerization, or polymer addition.

Double bonds break and form between carbon atoms, allowing polymer subunits to swap. One process, called ring-opening metathesis polymerization, opens carbon rings and elongates them into chains. The ...

Graft copolymers belong to the general class of segmented copolymers and generally consist of a linear backbone of one composition and randomly distributed branches of a different composition. They ...
