Novel polymers and processes for making same
Abstract
Abstract POLYMERS COMPRISING UNITS REPRESENTED BY THE FORMULA: 1-(R3-Q(-R4)-(R2)M-NH-CO-(NH)N-),2,5-DI(O=),3-R0,4-R1- PYRROLIDIN-3,4-YLENE WHEREIN R0 AND R1 EACH REPRESENT HYDROGEN ATOMS OR ALKYL GROUPS, AND R3 AND R4 ARE EACH A LOWER ALKYL GROUP OR R3 AND R4 CAN TOGETHER WITH Q REPRESENT THE ATOMS NECESSARY TO FORM A TERTIARY NITROGEN-CONTAINING HETEROCYCLIC GROUP; R2 REPRESENTS AN ALKYLENE GROUP, N IS 0 OR 1, M IS 0 OR 1, AND Q REPRESENTS A NITROGEN ATOM OR A CARBON RADICAL, WITH THE PROVISO THAT R3 AND R4 ARE TAKEN TOGETHER WITH Q TO REPRESENT A TERTIARY NITROGEN-CONTAINING HETEROCYCLIC GROUP WHEN Q IS A CARBON RADICAL, AND M CAN BE 0 ONLY WHEN Q IS A CARBON RADICAL. IN ONE ASPECT POLYMERS CONTAINING THE UNITS DEFINED ABOVE CAN BE MADE BY REACTING POLYMERS COMPRISING UNITS OF MALEIC ANHYDRIDE WITH A COMPOUND REPRESENTED BY THE FORMULA: R6-OOC-(NH)N-NH2 WHEREIN R6 IS A HYDROCARBON OF 1 TO 12 CARBON ATOMS AND N IS AN INTEGER OF 0 TO 1.
