Embodiment 1

[0123] Embodiment 1: Preparation of nonionic vinyl surfactant monomer

Embodiment 11

[0125] 376.8 g of polypropylene glycol monobutyl ether (molecular weight 1000) and 400 ml of toluene were charged to a 2 liter reactor equipped with a thermometer, heating mantle, temperature regulator, overhead stirring motor, nitrogen purge and condenser with Dean-Stark trap . The reactor contents were heated to reflux under nitrogen, and residual water was removed by water / toluene azeotrope into a Dean Stark trap. Cool the contents of the reactor to 90°C, add 0.04 grams of 2,6-di-tert-butyl p-cresol, 0.4 grams of dibutyltin dilaurate and 80 grams of isocyanate α, α-dimethyl - m-isopropylbenzyl ester. The reactor contents were held at 90°C for 60 minutes and then cooled to room temperature. Toluene was removed by roto-vac to obtain the nonionic vinyl surfactant monomer of Example 1.1.

Embodiment 12

[0127] Into a 2-liter reactor equipped with a thermometer, heating mantle, temperature regulator, overhead stirring motor, nitrogen purge, and condenser with a Dean-Stark trap was charged 588 g of polypropylene glycol tridecyl ether (molecular weight 1590) and 500 mL toluene. The reactor contents were heated to reflux under nitrogen, and residual water was removed by water / toluene azeotrope into a Dean Stark trap. Cool the contents of the reactor to 90°C, add 0.04 grams of 2,6-di-tert-butyl p-cresol, 0.4 grams of dibutyltin dilaurate and 80 grams of isocyanate α, α-dimethyl - m-isopropylbenzyl ester. The reactor contents were held at 90°C for 60 minutes and then cooled to room temperature. Toluene was removed by roto-vac to obtain the nonionic vinyl surfactant monomer of Example 1.2.

Abstract

Nonionic associative thickeners are provided having a nonionic water soluble polymer backbone containing vinyl addition polymer. The nonionic water soluble polymer backbone has at least two pendant polymeric chains attached to the nonionic water soluble polymer backbone. The pendant polymeric chains have terminal chain segments containing polyoxypropylene units. The nonionic associative thickeners are useful for modifying the rheology of compositions including aqueous compositions, such as latex containing compositions.

Description

technical field [0001] The invention relates to a nonionic associative thickener. In particular, the present invention relates to a nonionic associative thickener having a nonionic water-soluble polymer backbone comprising a vinyl addition polymer. At least two polymer side chains are connected to the main chain of the nonionic water-soluble polymer. The polymer side chains have terminal segments. Such nonionic associative thickeners can be used to modify the rheology of various compositions including water-based latex compositions such as paints, adhesives and paper coating compositions. Background technique [0002] In the formulation of water-based latex paints, the desired balance between high and low shear viscosities is sought to provide satisfactory application properties by e.g. spraying or brushing; satisfactory wet film leveling after application Resistant; minimal sagging of the wet film after application. Waterborne latex paints are generally formulated with ...
