Examples of 'supported metallocene' in a sentence
Meaning of "supported metallocene"
Supported metallocenes refer to a class of catalysts used in the production of specific types of polymers, particularly polyolefins. They offer enhanced control over the polymerization process, enabling the production of polymers with tailored properties such as high strength, thermal stability, and improved processability. The term 'supported' indicates that the metallocene catalyst is attached or immobilized onto a solid support material
