Can isoamyl octanoate replace white oil in emulsion polymerization?

This paper adopts isoamyl octanoate to replace white oil as the continuous phase of emulsion polymerization to synthesize the high molecular weight polyacrylamide emulsion RSE. S-80 and T-80 were chosen as the emulsifiers, and the test results showed that the HLB value is 5.72 when S-80/T-80 is 6.5. When S-80/T-80 is 6.5, the HLB value is 5.72.

Can emulsion polymerization reduce the consumption of fossil energy?

Emulsion polymerization is an effective means of synthesizing high-molecular-weight polymers in order to reduce the consumption of fossil energy. This paper adopts isoamyl octanoate to replace white oil as the continuous phase of emulsion polymerization to synthesize the high molecular weight polyacrylamide emulsion RSE.

Does acrylamide need a stable site in emulsion polymerization?

Acrylamide needs a stable site in emulsion polymerization. The emulsifier can reduce the interfacial tension between the ester and the water phase to form stable water-in-oil droplets.

Which emulsion is used to test interfacial tension of polyacrylamide?

An emulsion of the polyacrylamide (termed RSE) with ester compounds as the continuous phase was obtained. An SDT-500C spinning drop tensiometer was used to test the isoamyl caprylate–water interfacial tension using 0.5% solution prepared with emulsifiers with different hydrophilic–lipophilic balance (HLB) values.

How do you heat up a polyacrylamide emulsion?

The reaction system started to heat up using a cold water bath to control the maximum reaction temperature in the range of 38–42 °C for about 4 h. An emulsion of the polyacrylamide (termed RSE) with ester compounds as the continuous phase was obtained.

What is emulsion polymerization?

Recently, emulsion polymerization is an ideal method for obtaining high-molecular-weight polymers and plays an important role in preparing and applying polymer materials.
