Abstract: A method for improving holdout on a coated, cellulosic substrate, such as a man-made fiber board. The process comprises the steps of applying an aqueous carboxymethyl cellulose acetate butyrate size composition to a man-made fiber substrate, forming a sized substrate. The sized substrate is then dried. Next, an aqueous coating composition is applied to form a coated, sized substrate. The coated, sized substrate is then dried. According to the invention, the aqueous carboxymethyl cellulose acetate butyrate size composition used in the process comprises carboxymethyl cellulose acetate butyrate, water, and an organic solvent. The invention also relates to a sized, man-made fiber substrate comprising a man-made fiber substrate and a carboxymethyl cellulose acetate butyrate size. The carboxymethyl cellulose acetate butyrate may be either an internal sizing agent, or an external sizing agent.

Abstract: The invention provides a biodegradable polymer composition comprising a biodegradable polymer and a phenol-containing compound mixed with the polymer. The phenol-containing compound is present in the biodegradable polymer at an amount sufficient to slow the degradation rate of the biodegradable polymer. The invention also pertains to a method for slowing the degradation rate of a biodegradable polymer.

Abstract: A polyester resin composition is calendered to produce a film or a sheet. The polyester resin composition is a polyester having a crystallization half time from a molten state of at least 5 minutes combined with an additive for preventing sticking of the polyester to calendering rolls.

Abstract: This invention provides the composition, preparation, and end-use of waterborne crosslinking technology based compositions prepared from water-based latexes. The invention provides a water-based latex comprising dispersed, waterborne amino-functional polymer particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. In a preferred embodiment, a latex of the invention comprises dispersed, waterborne polymeric (polyamino)enamine (PPAE) particles; dispersed, waterborne acetoacetoxy-functional polymer particles; and water. The PPAE is the reaction product of a surfactant-stabilized acetoacetoxy-functional polymer (SAAP) and a poly(alkylenimine). The water-based latexes of the invention provide stable emulsions containing a blend of waterborne polymer particles which undergo crosslinking upon film formation. The latex films or coatings may be cured at ambient temperatures or may be thermally cured.
