摘要:
The present invention provides emulsion copolymers and coating compositions containing the same having improved room temperature and hot block resistance in coatings wherein the copolymers have a broad measured glass transition temperature and are the copolymerization product of a vinyl monomer composition A and a softer vinyl monomer composition B having a Hansch parameter of at least 3.2, and containing one or more vinyl monomer M, such that each of which vinyl monomer(s) M would when homopolymerized provide a homopolymer having a measured Tg of 20° C. or less, such as, for example, 2-ethylhexyl acrylate. In addition, the present invention provides methods for making the emulsion copolymers by a powerfeed process comprising feeding vinyl monomer composition A into a reactor from a feed vessel while feeding, simultaneously or after a delay, vinyl monomer composition B into the feed vessel while polymerizing the monomers in the reactor.
摘要:
A method of covering an anomaly in a wall substantially to match a pre-existing texture pattern surrounding the anomaly comprises the following steps. A valve is supported on a container assembly to define a main chamber. Contained material comprising wall material concentrate and propellant material is disposed within a main chamber defined by a valve and a container assembly. An actuator relative is arranged relative to the container assembly such that displacement of a button changes the valve from a closed configuration to an open configuration. A first portion of the contained material is applied to the anomaly. A second portion of the contained material is applied to the base coat. The second portion of the contained material forms a desired texture pattern on the base coat that substantially matches the pre-existing texture pattern.

Disclosed is a copolymer latex obtained by emulsion polymerization of a monomer mixture containing (a) 30-70% by mass of a conjugated diene monomer, (b) 0.1-15% by mass of an ethylenically unsaturated carboxylic acid monomer and (c) 15-69.9% by mass of one or more other copolymerizable monomers.

摘要:
Low viscosity, fast curing binders for nonwoven cellulosic materials comprise an aqueous dispersion of discrete particles of a highly functionalized emulsion copolymer resulting from the copolymerization of a water insoluble olefinic non-ionic organic compound, a water soluble olefinic carboxylate compound and a water soluble olefinic hydroxy ester or a water soluble olefinic amide or a mixture of hydroxy ester and amide. The emulsion copolymer dispersion is admixed with a latex to provide a binder having a relatively low viscosity and capable of reaching about 80 percent of fully cured wet tensile strength in 8 seconds or less.
