  • Low-foam alkali-stable amphoteric surface active agents
    Patent number: 4891159
    Abstract: Novel surface active agents of the formula: ##STR1## wherein R is selected from the group consisting of alkyl, aryl, alkylaryl groups of 2-18 carbons and alkoxymethyl wherein the alkoxy group is of 2-18 carbon atoms,R.sup.2 and R.sup.3 are individually selected from the group consisting of methyl; alkyl of 2 to 6 carbon atoms wherein said alkyl group is substituted by an electron-donating group on the beta carbon atoms thereof; polyoxyethylene and polyoxypropylene or R.sup.2 R.sup.3 may jointly form a --CH.sub.2 CH.sub.2 OCH.sub.2 CH.sub.2 -- or CH.sub.2 CH.sub.2 SCH.sub.2 CH.sub.2 -- group so as to form, together with the nitrogen atom to which they are bound, to form a morpholine or thiomorpholine ringQ is a covalent bond or ##STR2## wherein R.sup.1 is independently selected from the same groups as R.sup.2 and R.sup.

  • Polycationic block copolymer
    Patent number: 4719282
    Abstract: Novel polycationic block copolymers useful as antistatic agents in detergent formulations and as flocculating agents are obtained by first forming a block of units by reacting a monomer of the formula II ##STR1## wherein each of R.sub.5, R.sub.6, R.sub.7 and R.sub.8 may be the same or different and is selected from the group consisting of C.sub.1-3 alkyl, C.sub.1-3 hydroxy alkyl and polyoxyalkylene,m is an integer from 0 to 34 andr and s are the same or different and are integers from 1 to 6,with a molar excess of a dihalide of the formulaHal--L--Halwherein Hal represents a halogen atom and L is selected from--CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 --O--CH.sub.2 --, --(CH.sub.2).sub.t -- AND --CH.sub.2 CHOHCH.sub.2 --where t is an integer from 2 to 6 and thereafter reacting the product so formed with a compound of the formula III ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each individually selected from the group consisting of C.sub.
