摘要:
The invention relates to phosphoric esters of the general formula (I): wherein x is 1 or 2; n is a number from 2 to 18; m and n are each a number from 2 to 100; k is a number from 2 to 4; R″ is H or a linear or branched alkyl radical which may be substituted by a functional radical; and R′ is an alkyl, alkaryl, alkenyl or a sulfopropyl radical. The invention further relates to the use of the phosphoric esters as dispersants for pigments and fillers in aqueous or organic media and in particular to methods of forming a highly filled sheet molding compound or bulk molding compound comprising the step of dispersing components of the molding compound with said phosphoric esters.
摘要:
The invention relates to a release agent and lubricant for rubber moldings, especially radiator hoses, which comprises a polyether which is liquid at room temperature, has a viscosity from 400 to 2000 mPas and is obtained by addition reaction of ethylene oxide with oligo- and polyglycerols, individually or in a mixture as initial alcohols, in which reaction from 3 to 15 mol of ethylene oxide are added on per hydroxyl group.
摘要:
A process for the production of compact cellulose-containing moldings by reacting optionally modified organic polyisocyanates with cellulose, in particular lignocellulose, in the presence of mold release agents in an open or closed mold, wherein the mold release agents used are siloxane compounds containing aminopropyl groups and of the general formula (I) in which R1 is CH3 and/or R2, R2 is —(CH2)x—NH—R3 and/or —(O)y—(CH2)x—NH—R3′, R3 and R3′, independently of one another, may be H or —(CH2)x—NH2, R4 is —(CH2)x—NH—(CH2—CH2—O)z—R5 where R5 is an aryl or alkyl radical n is from 50 to 1000, m is from 0 to 20, with the ratio m:n=0 to 0.4, k is from 0 to 20, x is from 1 to 20, y is 0 or 1, z is from 1 to 20, with the proviso that at least one amino-functionalized radical is present.
摘要:
The invention relates to block-copolymeric polyalkylene oxides containing styrene oxide, obtained by alkoxylation, and their use as low-foam pigment wetting agents in aqueous pigment pastes with or without cosolvent and in aqueous and low-solvent coating materials and printing inks.

The invention relates to phosphoric esters of the general formula I where X is 1 or 2; n is from 2 to 18; m and o are each from 2 to 100; k is from 2 to 4; R″ is H or a linear or branched alkyl radical; and R′ is an alkyl, alkaryl, alkenyl, or sulfopropyl radical, and to there use as dispersants for pigments and fillers in aqueous or organic media.
摘要:
New alkoxylation products which carry alkoxysilyl groups, mostly in the form of (poly)ether alcohols or copolymers comprising polyether blocks, which are characterized in that the reactivity of the hydroxyl function is reduced, and also to processes for preparing them and to their use.
