Definitions

  • Emulsion polymers described herein comprise a shell portion comprising an alkali soluble resin (ASR), a core portion formed from polymerized units of at least one hydrophobic ethylenically unsaturated monomer, wherein no crosslinker is present when the shell portion and core portion are combined, and a nonionic water-soluble polymer.
  • ASR alkali soluble resin
  • the Tg of the core portion polymer is about -50 °C to about 60 °C.
  • the emulsion polymer exhibits a high level of PVOH grafting. This may be achieved by adding at least part of the PVOH in the process of polymerization, e.g., rather than making physical blends of PVOH with the post-polymerization core-shell latex.
  • emulsion polymers and/or spray dried powders may find use as part of cementitious compositions, improving, for example, one or more of: properties of the wet mortar, for example, water demand, density, and/or workability; and/or properties of the cured products, for example, adhesion, mechanical strength, tensile and elongation, crack bridging, and/or water uptake/resistance.
  • the cementitious composition comprises an emulsion polymer and/or spray dried powder as described herein and Portland cement.
  • the cementitious composition comprises an emulsion polymer and/or spray dried powder as described herein and a ternary hydraulic binder.
  • Polymer A was formed as follows. 500 g of Dl water was charged in a reactor (5-L round-bottom flask equipped/connected with a mechanical stirrer, a thermocouple, a condenser, and pumps for feeding monomer emulsions and additive solutions) and heated to 58°C. For Stage 1 polymerization, Example 1 A of ME#1 (from Example 1) was transferred to the reactor along with 34 g of Dl water as a rinse.
  • RDPs produced in Example 8 were subjected to drymix formulation and application testing.
  • the RDPs were blended in a ternary hydraulic binder (ordinary Portland cement (OPC) + calcium aluminate cement + gypsum, for fast setting) drymix formulation and the performance was evaluated for both the wet mortars (water demand, density, workability) and cured membranes (tensile and elongation, crack bridging, water uptake). Results are given in TABLE 5:
  • OPC ordinary Portland cement
  • gypsum calcium aluminate cement + gypsum
