  • Patent number: 4668763
    Abstract: New hydroxyl polyesters fluid at room temperature, with low viscosities at relatively high molecular weight and very low setting points have alkyl side chains in substantially regular arrangement along preferably unbranched or only slightly branched polyester chains, and are formed by the reaction of monocarboxylic acids and/or monoalkanols or their esters of ethers or polyester building components with additional polyester-forming derivatives. The new polyesters can be used to special advantage, after functionalization, for coatings or as adhesives. Especially advantageous is the fact that they can be used without solvents or with a very low solvent content.

  • Patent number: 4647651
    Abstract: A novel process is disclosed for producing fluorinated pyromellitate surfactants. The process comprises two primary steps. The first step involves reacting pyromellitic dianhydride with fluorinated alcohol at a mole ratio of about two moles of fluorinated alcohol per mole of pyromellitic dianhydride, thereby producing a pyromellitate having two fluorinated esters moieties and two carboxylic acid moieties. Thereafter, the fluorinated pyromellitate with carboxylic acid moieties is reacted with an oxirane compound in the presence of trimellitic anhydride to produce fluorinated pyromellitate mixtures having a reduced percentage of fluorine.

    Abstract: The invention provides a process for the production of polyetherester polyols which have hydroxyester groups terminally bound via ester groups to high molecular weight polyether polyol segments. These are produced by first reacting high molecular weight polyoxyalkylene ether polyols with molecular weights of from about 400 to 10,000 with an excess of dicarboxylic acids, dicarboxylic acid anhydrides or dicarboxylic acid esters, and then reacting the intermediate product in a further stage with an excess of diols, based on carboxyl groups.The new, high molecular weight polyetherester polyols thus consist of polyoxyalkylene ether segments, which have terminal ester segments in each case with terminal hydroxyl groups per end group.Moreover, the use is claimed of the high molecular weight polyetherester polyols as polyhydroxyl compounds for forming polyurethanes.

In the final step of the process, additional pyromellitic dianhydride is added to the reaction mixture so that the alcohol moieties may react with anhydride moieties to produce ester linking groups (between pyromellitate nuclei) and additional free acid moieties capable of reacting with the oxirane compound.

    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.

  • Patent number: 4383106
    Abstract: An elastomeric copolyester resin having high melt strength and capable of being blow-molded. The copolyester resin is made by adding to the polymerizing or initial mixture small amounts of a heat stable chain branching agent having three or more carboxyl groups, hydroxyl groups, or combinations thereof. The copolyester resin contains units of terephthalic acid, butane diol, polytetramethylene glycol, and dimer acid.

  • Patent number: 4377669
    Abstract: Photo-crosslinkable, novel polymers with side tricyclic imidyl groups, for example those of the formula ##STR1## are described. The novel photo-crosslinkable polymers are suitable for photo-mechanical applications, for example for the production of printing plates for the offset printing process and especially as photo-resists. They have high UV absorption and ensure a high rate of crosslinking even without the addition of photosensitizers.

  • Patent number: 4370452
    Abstract: A copolyester resin having modified carboxyl terminated ends is disclosed, as well as the method for making and using that compound with epoxide curing compounds in powder coating resins for substrates. The polymerization of the copolyester resin contains a reactor compounding stage which permits the reaction of the carboxyl termini with a curing reaction catalyst prior to any compounding or mixing of the modified copolyester resin with the epoxide curing compounds. The modification to these end groups of the copolyester resin creates activated termini which, although stable of themselves, react more rapidly, when the modified copolyester resin is compounded with the epoxide curing compounds and subsequently heated on the substrate, than with the conventional introduction of the epoxide catalyst during final compounding.

  • Patent number: 4365046
    Abstract: A copolyester resin having modified termini is disclosed, as well as the method for making and using that compound in subsequent reactions with epoxide curing compounds. The polymerization of the copolyester resin may include a compounding preparation stage for modifying the termini of the copolyester resin by reacting those end groups with an aromatic acid to alter the activation energy necessary to cure the modified copolyester resin with the epoxide compound upon mixing and heating of that mixture in a powder coating upon a substrate. The modified copolyester resin improves impact strength and leveling properties between 300.degree. and 450.degree. F., which is desirable for protection of the underlying substrate.
