Document Type and Number:
Japanese Patent JP2784604
Kind Code:
B2
Abstract:
Water soluble nonionic cellulose ethers are provided, containing mixed alkylphenoxyalkyleneoxy-2-hydroxy propylene groups, having hydrophilic units composed of (a) alkyleneoxy groups of two or three carbon atoms, in a number from zero to about six, selected from -CH2CH2O-; and -CH2CH2CH2O-; and (b) one 2-hydroxy propylene group, together with hydrophobic units which are alkylphenoxy groups of the formula where R and R4 are hydrocarbon groups having from about two to about thirty carbon atoms, preferably from about four to about eighteen carbon atoms; and so chosen that the total number of carbon atoms in the alkylphenoxy group is from 8 to 36, preferably from 10-24 carbon atoms; n1 is 0 or 1; connected linearly in a group of the general formula: n is zero to six A-O is alkyleneoxy as above Also provided is a class of cellulose ethers having similar hydrophilic units and hydrophobic units which are alkyloxy groups of the formula R-O- III where R is an alkyl group having from about eight to about thirty-six carbon atoms, preferably from about ten to about twenty-four carbon atoms, connected linearly in a group of the general formula R-O-[A-O]n-CH2 @@CH2 IV n is zero to six A-O is alkyleneoxy as above as well as water-base paints with excellent properties containing such cellulose ethers.
