Disclosed is a process for preparing copolymer dispersions made of alkylene oxides and glycidyl ethers according to formula (I) in which Ris hydrogen or a C-C-alkyl radical, Rand Rare an alkyl or aryl radical having 1 to 30 carbon atoms, and Ris an alkyl or aryl radical having 1 to 50 carbon atoms, which may also contain heteroatoms. A is an alkylene unit having 2 to 6 carbon atoms. In formula (1), x is a number from 0 to 10, y is a number from 0 to 10, n is a number from 0 to 100, k is a number from 1 to 100, Ris an acid group or hydrogen, and m is a number from 1 to 500, with the proviso that (y+n) must be at least 1.

Block copolymer by reacting alkylene oxide and glycidyl ether in presence of unsaturated monomer

Disclosed are copolymers made of alkylene oxides and glycidyl ethers according to formula (I) in which Ris hydrogen or a C-C-alkyl radical, Rand Rare an alkyl or aryl radical having 1 to 30 carbon atoms, and Ris an alkyl or aryl radical having 1 to 50 carbon atoms, which may also contain heteroatoms. A is an alkylene unit having 2 to 6 carbon atoms. In formula (1), x is a number from 0 to 10, y is a number from 0 to 10, n is a number from 0 to 100, k is a number from 1 to 100, Ris an acid group or hydrogen, and m is a number from 1 to 500, with the proviso that (y+n) must be at least 1.

Reacting alkylene oxide and glycidy ether to produce OH- or acid-terminated copolymer

The invention relates to copolymers of formula (I) wherein Ris hydrogen, a C-C-alkyl radical or C-C-alkenyl radical which can also contain heteroatoms, an acid group or an aliphatic or aromatic group comprising 1-50 carbon atoms, including an acid group, Rand Rindependently represent hydrogen, methyl and/or ethyl, n ranges from 0-100, and m ranges from 3 to 30, and k ranges from 1-200, and A is hydrogen, an acid group, a C-C-alkyl radical or a C-C-alkenyl radical which can also contain heteroatoms, an aliphatic or aromatic group comprising 1-50 carbon atoms, including an acid group, or a copolymer unit of formula (II), wherein Ris hydrogen, a C-C-alkyl radical or a C-C-alkenyl radical which can also contain heteroatoms, an acid group or an aliphatic or aromatic group comprising 1-50 carbon atoms, including an acid group, Ris hydrogen, methyl and/or ethyl, x ranges from 0 to 100, and y ranges from 3-30, wherein, if A is formula (2), Rrepresents hydrogen or an acid group. 

Copolymers containing styrene oxide and use thereof as emulsifiers and dispersing agents

Disclosed are copolymers made of alkylene oxides and glycidyl ethers according to formula (I) in which Ris hydrogen or a C-C-alkyl radical, Rand Rare an alkyl or aryl radical having 1 to 30 carbon atoms, and Ris an alkyl or aryl radical having 1 to 50 carbon atoms, which may also contain heteroatoms. A is an alkylene unit having 2 to 6 carbon atoms. In formula (1), x is a number from 0 to 10, y is a number from 0 to 10, n is a number from 0 to 100, k is a number from 1 to 100, C is an acid group or hydrogen, and m is a number from 1 to 500, with the proviso that (y+n) must be at least 1.
