Water-in-oil emulsions containing from 2% to 20% by weight of polymeric emulsifiers comprising statistical copolymers composed of units of the general formulae ##STR1## in the molar ratio of (I) to (II) of 2:1 to 20:1, wherein X is hydrogen or methyl, R.sub.1 is alkyl having 6 to 24 carbon atoms, and R.sub.2 is --NH--CH.sub.2 OH, --NH--CH.sub.2 CH.sub.2 OH, or --N(CH.sub.2 CH.sub.2 OH).sub.2 ; 20 to 75% by weight of water; and the remainder to 100% by weight of conventional oily substances used in cosmetic emulsions.
摘要:
In the process described, cyclic polyimino ethers with .DELTA..sup.2 -oxazoline or .DELTA..sup.2 -5,6-dihydro-4H-1,3-oxazine structure are applied, alone or together with cyclic monoimino ethers of the same type, or with lactones, plus cationic polymerization catalysts, to solid surfaces and polymerized by heating. The process gives smooth, glossy coatings with high adhesive strength, hardness, and elasticity.
摘要:
This invention concerns polyiminoethers of general formula (I) in which A is an aliphatic, aromatic or araliphatic group containing 4 to 40 carbon atoms and n free valencies at various carbon atoms, x may assume values of 0 to 40, n has a value of 2, 3 or 4, Z is either a direct bond or the group CR.sup.5 R.sup.6, the substituents R.sup.1 to R.sup.6 independently of one another are H, alkyl or aryl containing up 8 carbon atoms, the substituent R.sup.7 is hydrogen, methyl or ethyl and Q is a phenylene group, which may be substituted by one or two methyl groups, or the group --CHR--M--, where R is selected from the group consisting of H, alkyl or alkenyl and M is selected from the group consisting of alkylene, alkenylene, arylene and alkarylene, and the parts R and M of the molecule independently of one another contain 0 to 12 carbon atoms and, in addition, may be substituted by a C.sub.1-3 alkoxy group. These compounds are made from polyisocyanates of formula A(NCO).sub.n and cyclic monoiminoethers containing hydroxyl groups and are suitable for subsequent processing to polymers.
摘要:
In this process, cyclic polyimino ethers with a .DELTA..sup.2 -oxazoline or .DELTA..sup.2 -5,6-dihydro-4H-1,3-oxazine structure are polymerized by heating them alone or together with cyclic monoimino ethers of the same type, or with lactones, plus cationic polymerization catalysts. The new polymers are suitable for use as raw materials, foil materials, molding materials and hot-setting adhesives.

摘要:
The method of activating aqueous solutions of percompounds utilizing N-acylated uracils and benzouracils as activators; solid activated compositions comprising solid percompounds and N-acylated uracils and benzouracils as activators; and novel diacylated uracils and benzouracils.
摘要:
Water-in-oil emulsions wherein the emulsifier consists essentially of a copolymer or terpolymer of N-vinylpyrrolidone with a C.sub.6-24 alkyl or cycloalkyl acrylate or methacrylate, and vinyl acetate if desired, and the continuous phase is a cosmetically acceptable oily material which can be prepared easily, safely and inexpensively. The emulsions are substantially odorless and are cosmetically acceptable for the care of the skin.
