Abstract: Disclosed are crystalline polyesters having low melt viscosities, and thermosetting compositions comprising these polyesters. The compositions are especially useful as powder coatings. At least 40 mole percent of the acid moiety is a terephthalic or isophthalic acid moiety, and the polyester contains as moieties of the dihydric alcohol about 40-100 mole percent 1,6-hexanediol, the polyester being further characterized as having a molecular weight of about 700-3000, a melt viscosity of about 50-3000 cps at 160.degree. C. and a hydroxyl number of about 30-160.

Abstract: A process is provided for deactivation of catalyst residues in polyester compositions. The polyester compositions are provided by polymerizing diols and diacids, or mixtures of such diols and diacids, to form polyester compositions. The polymerization is carried out in the presence of a polymerization catalyst that leaves traces of such catalyst residues in the polyester composition. These catalyst residues can adversely affect the further processing and end use of the polyester composition. The present process provides deactivation of the catalyst residues by the use of a combination of a mono- or dihydrogen phosphonate or mono-, di-, or trihydrogen phosphate compound and a di- or triester phosphonate compound or a phosphite compound.

Abstract: Disclosed are crystalline polyesters having low melt viscosities and thermosetting compositions comprising these polyesters. The compositions are especially useful as powder coatings. The polyesters are derived from 1,4-butanediol and trans-1,4-cyclohexanedicarboxylic acid. The polyesters are characterized as having a molecular weight of about 700-3000, a melt viscosity of about 50-3500 cps at 160.degree. C. and a hydroxyl number of about 35-160. The thermosetting composition contains a curing agent which is reactive with the hydroxyl groups to crosslink the polyester.

Abstract: Cellulose propionate n-butyrate adapted to be mixed with an oil-modified alkyd resin to form a coating composition. The cellulose propionate n-butyrate has unique properties as an ingredient in such coating composition. The cellulose ester has a n-butyryl content of between about 3% and about 5%, a propionyl content of between about 40% and about 50% and a hydroxyl content of between about 2% and about 3%. The coating compositions are especially useful for protection and appearance when used as a coating on such items as wooden furniture.

Abstract: A composition comprised of poly(tetramethylene terephthalate), a polyetherester and a radial teleblock copolymer. This composition exhibits the combination of a desirable overall balance of general mechanical properties and an unobviously high impact strength.

Abstract: disclosed is a process for preparing containers, such as bottles, using a polyester of terephthalic acid, ethylene glycol, and 1,4-cyclohexanedimethanol, wherein the 1,4-cyclohexanedimethanol is from 25 to 40 mole percent of the diol. A molten parison of such polyester is extruded and then expanded in a mold to form the desired container.

Abstract: disclosed are compositions comprised of fine particles of unannealed poly(1,4-cyclohexylenedimethylene terephthalate) dispersed in a poly(tetramethylene terephthalate) type polyester, a poly(pentamethyleneterephthalate) type polyester, a poly(hexamethylene terephthalate) type polyester, a poly(1,4-cyclohexylenedimethylene terephthalate/isophthalate) type polyester, a poly(tetramethylene terephthalate) type polyester modified with poly(alkylene oxide)glycol, a poly(1,4-cyclohexylenedimethylene terephthalate) type polyester modified with poly(alkylene oxide) glycol or a polyester prepared from 1,4-cyclohexanedicarboxylic acid, dimer acid, and 1,4-cyclohexanedimethanol.
