Abstract: Disclosed is a shaped, thin-walled, thermoformed, heat-set article, the composition of which comprises:(a) a crystallizable polyester having repeating units from at least 90 mol % terephthalic acid and repeating units from at least 90 mol % 1,4-cyclohexanedimethanol, the total dicarboxylic acid mol % and the total glycol mol % each being 100 mol %, said polyester having an inherent viscosity of about 0.7-1.1, and(b) a heat stabilizing amount of an antioxidant system comprising a hindered phenol, a thio ester or ether and a phosphate salt.

Abstract: Sizing compositions comprising a terpolymer derived from(a) about 50 to about 70% by weight of at least one lower alkyl acrylate,(b) about 20 to about 40% by weight of at least one lower alkyl methacrylate, and(c) about 10% by weight acrylic acid or salt thereof.Such sizing compositions are especially useful when applied as a hot melt to a variety of filaments, yarns, fabrics, etc.

Abstract: Disclosed are adhesive compositions which are solid but spreadable to form a coating on substrates. Solutions of the adhesive composition are formed into a gel in a useful form such as a stick. The adhesive composition comprises dibenzal sorbitol gelling agent and polyesters derived from components (A), (B) and (C) as follows:(A) at least one dicarboxylic acid,(B) at least one diol, at least 20 mole percent of the diol component being a poly(ethylene)glycol having the formula H--OCH.sub.2 CH.sub.2).sub.n OH wherein n is an integer of from 2 to about 14, and(C) at least one difunctional dicarboxylic acid sulfomonomer containing a --SO.sub.3 M group attached to an aromatic nucleus, wherein M is Na.sup.+, Li.sup.+, K.sup.+ or a combination thereof, the sulfomonomer component constituting at least about 8 mole percent to about 45 mole percent of the sum of the moles of said components (A) and (C).

Abstract: Compositions suitable for use as hot-melt textile warp sizes are prepared by blending copolymers of ethylene and acrylic acid, methacrylic acid and the like, with selected low-molecular-weight additives, such as low-molecular-weight ethylene/acrylic acid copolymers, ethylene/methacrylic acid copolymers, and/or dicarboxylic acids, monoglycerides and waxes. These blends have low melt viscosities, can be readily applied to textile yarns with conventional hot-melt application equipment and set up rapidly to nontacky protective coatings on the yarns. After processing of the yarns, the new hot-melt sizes are readily removable using conventional securing procedures.
