Process

Ring-Opening Polymerization is defined as a Polymerization in which a Cyclic Monomer yields a Monomeric Unit which is acyclic or contains fewer cycles than the Monomer. Generally, the Ring-Opening Polymerization is carried out under mild conditions, and the By-Product is less than in the Polycondensation Reaction. A high molecular weight Polymer is easily obtained. Common Ring-Opening Polymerization Products includes Polypropylene Oxide, Polytetrahydrofuran, Polyepichlorohydrin, Polyoxymethylene, Polycaprolactam and Polysiloxane.
