HMP AM hydrophobically modified polyacrylamide hydrophobically modified polyacrylamide can be copolymerized with acrylamide and vinyl ether, vinyl ester, dodecyl methacrylate or N-alkyl acrylamide as the hydrophobic end , but this Associative thickeners are still in the laboratory stage, and their economics have yet to be demonstrated .
HAS E hydrophobically modified alkali-activated acrylic emulsion, like hydrophobically modified urethane ether (HEUR), provides a great platform in the field of thickeners. An example of the molecular structure of hydrophobically modified alkali-activated acrylic emulsion is shown in Figure 5-25.

Examples of molecular structure of hydrophobically modified alkali activated acrylic emulsion
(Meth)acrylic acid homopolymers and copolymers have higher chain segments composed of the following substances: unsubstituted (meth)acrylic acid or unsubstituted maleic fumarate which is polymerized by free radicals in the water phase Diacid or methylene succinic acid. As the pH value increases, the chain becomes ionic and dissolves in water. They become the water phase structure and thicken due to hydrogen bonding. In addition, its hydrophobic acrylate acrylate copolymer produces an association (L38), which changes from an increase in an aqueous phase to an association in an alkaline medium. This can be achieved by many methods. This largely depends on the structure of the polymer . Generally, the hydrophobically modified alkali activated acrylic emulsion has ethoxylated long-chain alcohol, which can be chemically combined with maleic acid L5a], (meth)acrylate 1541, propenyl ether 155 or urethane  monomer bond Combined. Ionic HAS E thickeners can be used for exterior wall coatings, which have relatively poor water resistance, but can be improved by ion crosslinking.
