摘要： A cellulosic product such as paper coating composition is disclosed comprising aqueous-based semi-crystalline vinyl acetate-ethylene polymer emulsions, containing crystalline ethylene segments, which are useful for imparting oil, grease, solvent, water, and moisture vapor resistance. The polymer emulsions are prepared via the direct aqueous-based free radical emulsion polymerization of ethylene with various other comonomers. The semi-crystalline aqueous-based polymer emulsions of this invention have a crystalline melting point and a crystalline heat of fusion ranging from 5 to 100 J/g. The semi-crystalline aqueous-based emulsion polymers of this invention can be used directly as a paper or paperboard coating for imparting oil, grease, solvent, water, and moisture vapor resistance. Further, the present invention provides a repulpable paper and paperboard.

摘要： The following method is used to measure the adhesion of a polymer binder to a heated metal surface:A metal plate is attached to a heated (350° F.; 177° C.) platform and allowed to equilibrate to the temperature of the platform. A polymer emulsion binder is applied to a substrate, such as cotton fabric, and an end of the coated substrate is attached to a tensile measuring apparatus. The coated side of the coated substrate is pressed onto the heated metal plate; e.g., using a 3-lb lab roller. After a length of time to cause drying and/or partial cure of the binder (approximately 30 seconds), the metal plate and the tensile measuring device are separated at a given uniform speed. The amount of force needed to remove the substrate from the metal plate is recorded.
