Constrained geometry complex
open-in-new
<p>In <a href="/facts/Organometallic_chemistry/bhqFz2P0">organometallic chemistry</a>, a "constrained geometry complex" (CGC) is a kind of catalyst used for the production of <a href="/facts/Polyolefin/hWl2j3r0">polyolefins</a> such as <a href="/facts/Polyethylene/LaaAf4cn">polyethylene</a> and <a href="/facts/Polypropylene/HM9PvoCz">polypropylene</a>. The catalyst was one of the first major departures from <a href="/facts/Metallocene/AecA5Qrk">metallocene</a>-based catalysts and ushered in much innovation in the development of new plastics. </p>
