Prepolymer - Names and Identifiers
Prepolymer - Introduction
Prepolymer refers to a polymer compound composed of relatively short polymer segments. Its properties depend on the monomers used and the polymerization conditions. In general, Prepolymer have a lower molecular weight, a lower relative molecular mass, and a higher reactive group content.
Prepolymer are widely used, especially in the fields of polyurethane and polyester. They can be used as precursors for polymers to further prepare polymers of larger molecular weight. In polyurethane articles, Prepolymer are commonly used as raw materials for elastomers, coatings, adhesives, sealants, foams, and the like.
The preparation method of Prepolymer varies depending on the type of compound. A common method is to form a Prepolymer by adding an excess of monomer to the polymerization reaction to cause condensation reaction with the reactive group. In addition, the Prepolymer can also be produced by a method such as solution polymerization or melt polymerization.
