| titleOfInvention | COPOLIMEROS THAT ASSOCIATE IN A HYDROPHOBE FORM |
| abstract | Water-soluble copolymers that are hydrophobicly associated, containing novel monomers that are hydrophobicly associated. The monomers comprise an ethylenically unsaturated group, as well as a polyether group with a block structure formed of a hydrophilic polyalkylene block, consisting substantially of ethylene oxide groups, and a terminal hydrophobic polyalkylene oxide block, consisting of alkylene oxides with at least 4, preferably, at least 5 carbon atoms. Claim 1: Water-soluble copolymer that is hydrophobicly associated, comprising at least the following monomers: (a) 0.1 to 20% by weight of at least one monoethylenically unsaturated monomer, which is hydrophobicly associated (a) , as well as (b) 25% by weight to 99.9% by weight of at least one monoethylenically unsaturated, hydrophilic monomer, which differs from the above (b), referring the amounts indicated in each case to the total amount of all monomers in the copolymer, characterized in that at least one of the monomers (a) is a monomer of the general formula (1): H2C = C (R1) -R4-O - (- CH2-CH (R2) - O-) k - (- CH2-CH (R3) -O-) l-R5 (1) where the units are - (- CH2-CH (R2) -O-) ky - (- CH2-CH (R3) - O-) l arranged in block structure in the order indicated in formula (1) and having the radicals and the index the following meanings: k: a number from 10 to 150, l: a number from 5 to 25, R1: H or methyl, R2: independently of each other, H, methyl or ethyl or, being precise, that at least 50 mol% of the radicals R2 mean H, R3: independently of each other, a hydrocarbon radical with at least 2 carbon atoms or an ether group of the general formula -CH2 -O-R2 ', where R2' represents a hydrocarbon radical with at least 2 carbon atoms, R4: a single bond or a divalent, linking group, selected from the group of - (CnH2n) - [R4a], -O- (Cn'H2n ') - [R4b] and -C (O) -O- (Cn''H2n' ') - [R4c], where n, n' and nö each time represent an integer from 1 to 6, R5: H or a hydrocarbon radical with 1 to 30 carbon atoms. |
