Soap-Free Emulsion Polymerization for New Building Sealant

摘要

In order to obtain functional polymer latex with surface carboxyl groups which can enhance colloidal stability and alkali viscosity, a molecular design was carried out and novel latex for building sealant was synthesized by using the technology of soap-free emulsion and core-shell polymerization. The monomer component, initiator, reaction temperature, adding mode of raw materials, carboxylation of colloidal particle and application of cross-linking reaction in molecular design were investigated. The suitable formula and process conditions were defined.
