    摘要： Crosslinked polymers are produced by the reaction of a linear polyquinoxaline containing a pendant furan group with an aromatic olefinic end-capped compound. The polyquinoxaline polymers have an alicyclic endooxy linkage repeated throughout the polymer at the cross-linking sites where the furan end-capped constituent undergoes a Diels-Alder reaction with the aromatic olefinic endcapped crosslinking agent. Subsequently, the alicyclic endooxy linkage may be aromatized by the application of heat to produce a high performance polymer which is suitable for use in severe environments at temperatures up to 400*C.

    摘要： A SYNTHETIC LINEAR WATER-SOLUBLE POLYAMIDE IS FORMED BY THE REACTION OF EQUIMOLAR PROPORTIONS OF IMINODIACETONITRILE ANDFORMALDEHYDE IN THE PRESENCE OF AN ACID AND WATER TO FORM A POLYAMIDE WHICH IS WATERSOLUBLE IN THE BASE FORM OR THE ACID SALT FORM. THE POLYAMIDE CAN BE REACTED WITH ACRYLONITRILE, ACRYLAMIDE OR ACRYLIC ACID TO PUT A SUBSTITUENT ON THE SECONDARY AMINE NITROGEN. THE NITRILE OR THE AMIDE MAY BE HYDROLYZED TO THE ACID WHICH READILY FORMS SALTS. ALL PRODUCTS ARE WATER SOLUBLE.

REPRESENTATIVE DICARBOXYLIC ACID DIHYDRAZIDES ARE ADIPIC ACID BISHYDRAZIDE, SEBACIC ACID BISHYDRAZIDE, POLYACRYLIC ACID HYDRAZIDE AND TEREPHTHALIC ACID BISHYDRAZIDE. THE CROSS-LINKING AGENT MAY BE USED TO THE EXTENT OF 0.01 TO 50% BY WEIGHT, BASED ON THE WEIGHT OF THE UNCROSS-LIKED POLYMER. BY USING SUCH CROSS-LINKING AGENTS, GOOD CONTROL OF MOLECULAR WEIGHT AND CONSEQUENTLY OF THE FLOW PROPERTIES OF THE CROSS-LINKED COPOLYMER ARE OBTAINED. THE CROSSLINKED POLYMERS ARE ALSO CLAIMED.

    摘要： Fatty alkyl succinate ester and succinimide modified copolymers of ethylene and an alpha-olefin, such as an ethylene-propylene copolymer, are useful as shear stable viscosity index (VI) improvers, dispersants and pour point depressants in lubricating oils. Especially useful is the succinate ester of mixtures of primary n-alkanols containing about 12 to about 18 carbon atoms and the N-(3-dimethylaminopropyl) succinimide derivative of the copolymer of ethylene and an alpha-olefin, such as an ethylene-propylene copolymer. This succinate ester-succinimide derivative is prepared by reacting the copolymer in an aromatic solvent with maleic anhydride in the presence of a free radical initiator, then esterifying the anhydride with a fatty alcohol or mixtures thereof in the presence of an acidic catalyst and finally converting any unreacted anhydride and half esters to the succinimide by reaction with a polyamine containing a primary amine. Additive concentrates containing 5 to 30 wt. % of the copolymer derivative in a solvent facilitate the introduction of the additive into a lubricating oil blend.
