Polymerization Initiators (186)

Polymerization initiators are substances that trigger polymerization reactions by producing free radicals or ions. They play a key role in various polymerization methods, such as free radical, cationic, and anionic polymerization. Depending on the method used, these initiators can operate through thermal, photochemical, or redox mechanisms. They are crucial for synthesizing high-performance polymers like polyurethanes and polyesters. Typical examples include peroxides, azo compounds, and sulfonyl chlorides.
