A waterborne acrylate-functionalized alkyd coating composition is disclosed, which includes an acrylate-functionalized alkyd resin, at least one drier, and water. The acrylate-functionalized alkyd resin comprises the reaction product of (i) a hydroxy functional alkyd resin, (ii) an acid anhydride, and (iii) a glycidyl acrylate. Methods of preparing waterborne acrylate-functionalized alkyd coating compositions are also disclosed.
摘要:
This invention provides polymers useful in coating compositions. The polymers are prepared via a free radical polymerization using ethylenically unsaturated monomers. The polymers of this invention possess pendant allylic groups which are capable of effecting free-radical flux when the compositions are applied to a substrate and exposed to oxygen. Coatings formed from preferred compositions possess superior solvent, print, and block resistance.

Various fibrous articles incorporating a water non-dispersible short-cut polymer microfiber are provided. The water non-dispersible short-cut polymer microfibers can be incorporated into a number of different fibrous articles including personal care products, medical care products, automotive products, household products, personal recreational products, specialty papers, paper products, and building and landscaping materials. In addition, the water non-dispersible short-cut polymer microfibers can be incorporated into nonwoven webs, thermobonded webs, hydroentangled webs, multilayer nonwovens, laminates, composites, wet-laid webs, dry-laid webs, laminates, composites, wet laps, woven articles, fabrics and geotextiles. These various end products can incorporate the water non-dispersible short-cut polymer microfibers in varying amounts based on the desired end use.
摘要:
A paperboard and a cardboard comprising at least one nonwoven web layer are provided. The nonwoven web layer comprises a plurality of first fibers, a plurality of second fibers, and a binder. The first fibers comprise a water non-dispersible synthetic polymer and have a different configuration and/or composition than the second fibers. The first fibers have a length of less than 25 millimeters and a minimum transverse dimension of less than 5 microns. The nonwoven web layer comprises at least 1 weight percent of the first fibers, at least 10 weight percent of the second fibers, and at least 1 weight percent of the binder. The paperboard and cardboard can incorporate a large amount of post consumer recycled fibers and still exhibit high strength and durability. Also disclosed is a process for producing the first fibers and the multicomponent fibers from which they are derived.

摘要:
A short-cut, water non-dispersible polymer microfiber is provided comprising at least one water non-dispersible polymer wherein the water non-dispersible polymer microfiber has an average fineness of less than 1 denier per filament; and wherein said water non-dispersible short-cut polymer microfiber has an aspect ratio of about 300 to about 1000. A process for producing water non-dispersible polymer microfibers and a process for producing nonwoven articles are also provided.
摘要:
A versatile binder comprising at least one or more sulfopolyesters is provided. These sulfopolyester binders can enhance the dry tensile strength, wet tensile strength, tear force, and burst strength of the nonwoven articles in which they are incorporated. Additionally, the water permeability of these binders can be modified as desired by blending different types of sulfopolyesters to produce the binder. Therefore, the binder can be used in a wide array of nonwoven end products and can be modified accordingly based on the desired properties sought in the nonwoven products.
