Examples of 'polymerization solvent' in a sentence
Meaning of "polymerization solvent"
polymerization solvent - A polymerization solvent is a substance used in polymer chemistry to dissolve monomers and facilitate the polymerization process. It plays a crucial role in the formation of polymers by promoting the reaction between monomeric units and controlling the characteristics of the resulting polymer
