[0087] Preparation of polymerizable surfactants

example 1

[0088] Example 1. Polymerizable Surfactant C 12 C 14 - Preparation of 2.6AGE-15EO ammonium sulfate salt

[0089] 10.0 g of 45% potassium hydroxide solution was added to 320 g of Alfol 1214 and stirred in the reactor at 80°C with nitrogen purging under the surface. After heating to 100°C, the gas flow was stopped and the flask was evacuated to approximately 20"Hg using a vacuum pump. After one hour, the vacuum was broken with nitrogen and a sample was analyzed by Karl-Fischer titration for a moisture content of 0.09%.

[0090] In the temperature range of 95°C - 105°C, 470.1 g of allyl glycidyl ether was added to the reactor within 120 minutes. After 30 minutes, the reactor contents were heated to 120°C. After an additional six hours at a temperature ranging from 120°C to 123°C, a sample of the reactor contents was titrated to a naphthol benzyl alcohol indicator using 0.1 M perchloric acid in acetic acid and in the presence of tetrabutylammonium bromide A basicity of 0.101 m...

example 2

[0094] Example 2. Preparation of polymerizable surfactant Nopol-2.6AGE-15EO ammonium sulfate

[0095] 11.1 g of 45% potassium hydroxide solution were added to 283 g of nopol alcohol and stirred in the reactor at 100° C. with a nitrogen blanket. The gas flow was stopped and the flask was evacuated to approximately 22"Hg using a vacuum pump. After one hour, the vacuum was broken with nitrogen and a sample was analyzed by Karl-Fischer titration for a moisture content of 0.06%.

[0096] In the temperature range of 93°C-96°C, 505.8 g of allyl glycidyl ether was added to the reactor over 120 minutes. After 30 minutes, the reactor contents were heated to 120°C. After an additional five hours in the temperature range of 118°C-120°C, a sample of the reactor contents was titrated to a naphthol benzyl alcohol indicator using 0.1 M perchloric acid in acetic acid and in the presence of tetrabutylammonium bromide A basicity of 0.125 mmol / g was exhibited, indicating essentially complete re...

Abstract

Disclosed are ethylenically unsaturated salts of allyl (poly)ether sulfates utilized as reactive surfactants or emulsifiers during emulsion polymerization.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 842,806, filed May 3, 2019. [0003] field of invention [0004] The present invention relates to polymerizable surfactants which are useful in the preparation of polymers by emulsion polymerization. Background technique [0005] Surfactants are used in a variety of applications for, for example, dispersing, emulsifying, wetting, and foaming, across many industries such as coatings, adhesives, home care, personal care, construction, paper, inks, and the like . Surfactants are frequently included in products such as paints and coatings because these surfactants are necessary to stabilize these products or during the manufacture of the products. Frequently, however, the presence of surfactants in the final product negatively affects the desired properties in such final product. In painting, for example, the presence of too much surfactant may cont...
