摘要： Novel polyimides, optionally end-capped with polymerizable or inert groups, and the polyamic acid or ester intermediates thereof are prepared by reacting a tetracarboxylic acid compound (e.g. pyromellitic dianhydride or 3,3',4,4'-benzophenone tetracarboxylic acid dianhydride or its methyl diester) with diamines having the general formula ##STR1## wherein Z is oxygen or sulfur, X and/or Y are carbonyl or carbinol groups, the amine groups may be in the 2-, 3-, and/or 4-position, and isomerism is present when X and/or Y is a carbinol group. The polyimides may be end-capped by reaction, during or after their formation, with polymerizable groups such as 3-aminophenyl acetylene or 3,6-endomethylene-1,2,3,6-tetrahydrophthalic anhydride. The diamines are novel classes of amines when Z is sulfur and when Z is oxygen and X, Y, or X and Y are carbinol groups.

摘要： An adhesive composition based on 2-cyanoacrylate esters contains as an anionic polymerization inhibitor an acid chelate formed of boric acid or a derivative thereof and a selected polyhydroxy compound. The chelate is conveniently formed in situ in the 2-cyanoacrylate ester, but may also be prepared separately and added to the ester directly. An exemplary acid chelate used as stabilizer is prepared from boric acid and pyrogallol. The resulting stabilized adhesive compositions have a rapid cure rate and may be used on a wide variety of substrates.

摘要： Hot melt adhesive compositions are prepared from 20 to 98% by weight of a polylactide homo- or copolymer containing at least 20 molar percent of the lactide component; 2 to 80% by weight of a polar tackifier having a Ring and Ball softening point (as described by ASTM E-26) greater than about 60.degree. C.; 0 to 50% by weight of a plasticizer; 0 to 30% by weight of a wax diluent; 0-3% by weight of a stabilizer; and 0-20% of starch. By utilizing a naturally occurring, thermoplastic, biodegradable copolymer as the base polymer, these adhesives advance the state of the art of hot melt adhesives by alleviating the dependence on petroleum based materials and by allowing for the development of hot melt adhesives which either degrade naturally after coming in contact with the soil or which can be composted.
