The disclosure relates to ethylenic polymers containing repeat units having pendant groups that can be linked to an ethylenic backbone via ester groups, such as those resulting from vinyl alkanoate monomers and alkyl (meth)acrylate monomers. The ethylenic polymer generally includes first repeat units in combination with one or more of second repeat units, third repeat units, and fourth repeat units. The first repeat units can include vinyl alkanoate monomer residues, the second repeat units can include alkyl (meth)acrylate residues, the third repeat units can include pendant carboxylic groups, and the fourth repeat units can include pendant aromatic groups. The combined structure of the ethylenic polymer is suitable for the formation of high-solids aqueous emulsions or dispersions, which can be used to apply a waterborne coating to a substrate such as paper. The ethylenic polymer and coatings therefrom can provide good water resistance, good oil resistance, recyclability, repulpability, and/or biodegradability.

Sprayable joint compound compositions, building construction assemblies and methods, including methods for finishing joint seams and methods for installing interior walls and ceilings, the sprayable joint compound compositions having a thixotropic property and the sprayable joint compound compositions comprising a combination of a thixotropic rheological modifier, a polyacrylic dispersant and a hydrophobic lightweight filler.

A thermal receiver for image production. The thermal receiver maintains advantageous properties such as surface tension while being made with chemicals with fewer health, safety, and environmental concerns than previous thermal receivers. This includes the elimination of hazardous catalysts and PFAS/fluorinated surfactants from the composition through the use of silicone compatibilizers and trisiloxane surfactants. The composition has low surface tension within a short time frame after being applied to a surface.

This application provides a novel waterborne non-isocyanate polyurethane (NIPU) dispersion comprising an NIPU prepared using an amidoamine, a cyclic carbonate, and a dispersing agent, as well as a method of making the waterborne NIPU dispersion.
