CEMENT MODIFIER COMPOSITIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17442845 titled 'CEMENT MODIFIER COMPOSITIONS
The abstract describes emulsion polymers, spray dried powders, and cementitious compositions made with these materials. The emulsion polymers consist of an alkali soluble resin in the shell portion, polymerized units of hydrophobic ethylenically unsaturated monomers in the core portion, and a nonionic water-soluble polymer.
- Emulsion polymers have a unique structure with a shell portion containing an alkali soluble resin and a core portion made of hydrophobic monomers.
- The absence of a crosslinker in the combined shell and core portions is a key feature of these emulsion polymers.
- Spray dried powders can be made using the emulsion polymers, offering a convenient form for various applications.
- The emulsion polymers and spray dried powders can be used in cementitious compositions, enhancing their properties and performance.
- The inclusion of a nonionic water-soluble polymer in the emulsion polymers provides additional benefits in various applications.
