Polyester blends containing recycled, post-consumer polyethylene terephthalate are described. The blends have the advantage of being miscible (visually clear) and remaining clear after post-extrusion heat histories.

Miscible polyester blends utilizing recycled polyesters

Disclosed are water-dispersible fibers derived from sulfopolyesters having a Tg of at least 25&#xb0; C. The fibers may contain a single sulfopolyester or a blend of a sulfopolyester with a water-dispersible or water-nondispersible polymer. Also disclosed are multicomponent fibers comprising a water dispersible sulfopolyester having a Tg of at least 57&#xb0; C. and a water non-dispersible polymer. The multicomponent fibers may be used to produce microdenier fibers. Fibrous articles may be produced from the water-dispersible fibers, multicomponent fibers, and microdenier fibers. The fibrous articles include water-dispersible and microdenier nonwoven webs, fabrics, and multilayered articles such as wipes, gauze, tissue, diapers, panty liners, sanitary napkins, bandages, and surgical dressings. Also disclosed is a process for water-dispersible fibers, nonwoven fabrics, and microdenier webs. The fibers and fibrous articles have further applications in flushable personal care and cleaning products, disposable protective outerwear, and laminating binders.

New compositions for forming films for use in optical devices are provided. The compositions comprise a cellulose and a crosslinking agent dissolved or dispersed in a solvent system. Preferred celluloses are cellulose esters such as cellulose acetates, cellulose triacetates, cellulose acetate phthalates, and cellulose acetate butyrates. Preferred crosslinking agents are triazines such as those derived from melamine and benzoguanamine. The inventive compositions can be used to form, for example, protective and/or compensation films for use in polarizing plates.

Water-dispersible and multicomponent fibers from sulfopolyesters

Disclosed are polymer compositions having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about &#x2212;0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce oxygen-scavenging compositions.
