Development and Preparation of Thickening Bedplate Agent

The thickening bedplate agent was preparaed by the semi-continuous emulsion polymerization. The effect of the emulsion thickening based on the choice of monomer was mainly investigated. The experimental results showed that the fight contents of acrylic acid can make the emulsion thickening better when the ratio of 2-EHA to Vac is 7/1. Choosing the right method and adding the proper contents of thickening agent can better heighten the emulsion thickening.
