Definitions
- the subject of the present patent application is a new process for the preparation of water-soluble graft copolymers.
- the international application WO 00/40958 describes a process for preparing copolymers of acrylamide and of poly (N-isopropyl acrylamide), including the following successive steps:
- telomere obtained x -NH 2 by precipitation in ether, filtration and drying;
- the invention relates to a process for preparing a comb copolymer whose skeleton is of acrylamide, acrylic acid, acryloylamino ethanol or dimethylacrylamide type, on which poly (N) side segments are grafted.
- -alkyl acrylamide) or poly (N, N-dialkyl acrylamide) characterized in that it comprises the following successive stages:
- step (b) isolating the telomere of formula (I) obtained in step (a);
- R 5 represents a hydrogen atom or a methyl radical and in a molar ratio (IV) / (III) less than or equal to 10 and greater than or equal to 1 while maintaining the pH of the reaction medium at a value between 6 and 13 and preferably between 7 and 8 to obtain a macromonomer of formula (V):
- step (e) the copolymerization in water of the macromonomer of formula (V) isolated in step (d) with a monomer chosen from acrylamide, acrylic acid, acryloylaminoethanol or dimethylacrylamide and, if desired, (f) Purification of the copolymer obtained.
- radicals R 3 and R 4 represent a linear or branched alkyl radical representing from 1 to 4 carbon atoms
- these include radicals methyl, ethyl, propyl, 1-methylethyl (isopropyl), butyl, 2-methylpropyl (isobutyl), 1-methylpropyl (sec-butyl) or 1,1-dimethylethyl (tert-butyl).
- the radicals R 3 and R 4 each represent an isopropyl radical and the process as defined above therefore has the object of preparing a comb copolymer whose skeleton is of the acrylamide, acrylic acid, acryloylaminoethanol or dimethylacrylamide type on which are grafted poly (N-isopropyl acrylamide) side segments.
- R 1 is more particularly a divalent alkane-di-yl radical such as, for example, a methylene radical, 1,2-ethane-di- 1, 3-propanediyl or 1,4-butanediyl.
- the process as defined above relates to the preparation of a comb copolymer whose skeleton is of the acrylamide or dimethylacrylamide type, on which are grafted poly (N-alkyl acrylamide) or poly ( N, N-dialkyl acrylamide).
- step (b ) the pH is adjusted the reaction medium resulting from step (a), without isolating the telomer of formula (I), at a value of between 6 and 13, and preferably between 7 and 8;
- step (c 1 ) adding to the reaction medium resulting from step (b 1 ), the acid chloride of formula (IV), in a molar ratio (IV) / (III) less than or equal to 10 and greater than or equal to to 1 by maintaining the pH in the range indicated in step (b 1 ), to obtain the macromonomer of formula (V).
- the steps (a) to (c 1 ) are preferably carried out in a single pot.
- the monomer chosen from acrylamide, acrylic acid, acryloylaminoethanol or dimethylacrylamide
- the steps (a), (c) and (e) are carried out in a single pot.
- the subject of the invention is a comb copolymer whose skeleton is of the acrylamide or dimethylacrylamide type, on which are grafted poly (N, N-dialkylacrylamide) side segments and more particularly a comb copolymer whose skeleton is of the acrylamide or dimethylacrylamide type, on which are grafted poly (N, N-dimethylacrylamide) side segments.
- thermoset reactor is poured into a concentrated aqueous solution at 1.77 moles per liter of N-isopropylacrylamide (NIPAM), which is stirred under a bubbling step. nitrogen for about 1.5 hours.
- NIPAM N-isopropylacrylamide
- 2-aminoethanethiol hydrochloride AET, HCl is then added in a determined NIPAM / AET.HCl molar ratio ranging from 30 to 75.
- HPLC high performance liquid chromatography
- the telomer is recovered in solid form on which the dosage of alkalinity (potentiometric dosage).
- the reaction medium obtained comprises about 16.4% by weight of poly (N-isopropyl acrylamide) telomer.
- Acryloyl chloride (AcrCl) (molar equivalence determined with respect to the 2-aminoethanethiol introduced in the previous step) is then added dropwise to the medium maintained at a temperature of 10 ° C. and at a pH between 7 and 8 by adding normal potash. After introduction of the acid chloride, the reaction medium is stirred for at least 1 hour, by rectifying if necessary the pH.
- the acylation rate is determined by assaying the alkalinity of the purified macromonomer.
- the same remark as above can be made insofar as the extraction of the macromonomer proves difficult.
- the determination of the residual acrylic acid resulting from the hydrolysis of the excess acryloyl chloride was also carried out.
- a solution of acrylamide (AM) at 50% by weight is added and then the whole is diluted with deionized water in order to obtain monomer concentration of about 10% by weight in specific proportions.
- a nitrogen barb is applied for 2 hours at the bottom of the reactor.
- Ammonium persulphate (0.18% by weight relative to the monomers) is added followed by a solution of sodium metabisulphite (0.43% by weight relative to the monomers) for 30 minutes and the medium is left undisturbed. stirring for 4 hours while maintaining the temperature less than or equal to 30 ° C.
- the residual acrylamide level is around 1,000 ppm.
- This telomer is obtained according to the method described in step (1) of the example
- telomere in solution in water at a concentration of 16.2% is obtained.
