Definitions
- the present invention relates to a process for the preparation of amphiphilic copolymers by controlled radical polymerization, in the presence of a RAFT agent (Reversible Addition Fragmentation Transfer).
- the copolymers of the invention have low polymolecularity indices, low viscosities in solution, and are readily soluble in alkaline medium.
- RAFT agent Reversible Addition Fragmentation Transfer
- the copolymers of the invention have low polymolecularity indices, low viscosities in solution, and are readily soluble in alkaline medium.
- it is commonly used with copolymers, especially based on styrene, acrylic acid, etc.
- latexes and paints in particular, it is further important that said copolymers are soluble in alkaline media.
- amphiphilic copolymers obtained by the "conventional" radical route generally have a relatively high polydispersity index (IP), as indicated, for example, in the patent application EP 0 697 422.
- IP polydispersity index
- This application describes a method for the solution polymerization of a copolymer of styrene (or substituted styrene) with a monomer having carboxylic functions, as well as the use of the copolymers obtained in surface cleaning solutions.
- These copolymers have number-average molar masses (Mn) of between 500 g / mol and 50000 g / mol and high polymolecularity indices (typically between 1.8 and 7.5).
- the controlled radical polymerization based on RAFT agent is already known, in particular from the publications of international applications WO 98/01478, WO 99/05099 and WO 99/31144 which advocate the use of certain sulfur molecules of the family of dithioesters , dithiocarbonates, dithiocarbamates and trithiocarbonates as transfer agents to obtain (co) polymers with narrow polymolecularity indices and describe the polymerization process termed "reversible addition-fragmentation polymerization".
- the article Macromolecules, (2007), 40 (17), 6181-6189 describes the synthesis of polystyrene-b-poly (acrylic acid) block copolymers from two RAFT agents (of the asymmetrical trithiocarbonate type).
- the block copolymers thus obtained are of variable compositions (20 to 50 acrylic acid units and 10 to 50 n-butyl acrylate units) with a number-average molecular mass (Mn) of less than 9000 g / mol and characterized by an index of polymolecularity included between 1.4 and 2.3.
- Mn number-average molecular mass
- This article shows that the synthesis of amphiphilic copolymers by controlled radical polymerization using RAFT agents is possible. However, only low solids block copolymers were obtained.
- the article Macromolecules, (2006), 39, 8632-8638 describes the synthesis of an acrylic acid / styrene gradient copolymer by controlled radical polymerization, with a RAFT agent, said copolymer then being used directly as a seed for synthesis. in emulsion of polystyrene or poly (n-butyl acrylate).
- the gradient copolymer is obtained in several steps, one of which consists of adding water to the copolymer obtained in the form of a gel, until spontaneous phase inversion and obtaining a translucent solution.
- the amount of water added is important since the level of solid disclosed is of the order of 12% by weight.
- the initial gel as well as the translucent solution contain a high residual amount of monomers (about 45% by weight in the gel).
- a further step of converting the residual monomers at 60 ° C. for 12 hours is necessary to obtain a conversion of 94% by weight. This multi-step process over a long period of time is also not suitable for industrial use.
- Another object of the invention is to provide a high efficiency process for the synthesis of amphiphilic gradient copolymers which are soluble in alkaline media and have a low polydispersity index and a high solid content.
- Another object of the invention is to provide a process for the synthesis of copolymers with amphiphilic gradients, soluble in alkaline media, whose polymolecularity index is low, and with a high solid content, said process being easily industrialized, weakly energy consumer.
- the present invention relates to a process for preparing an amphiphilic gradient copolymer by controlled radical polymerization, in the presence of a Reversible Addition Fragmentation Transfer (RAFT) agent comprising at least the following steps: a) preparation a reaction medium comprising at least one radical-polymerizable hydrophilic monomer, at least one radical-polymerizable hydrophobic monomer, at least one RAFT agent, at least one initiator, and optionally at least one solvent; b) heating the reaction medium with stirring at a temperature between 40 0 C and 150 0 C, preferably between 50 0 C and 140 0 C, preferably between
- RAFT Reversible Addition Fragmentation Transfer
- the hydrophilic monomer radically polymerizable is selected from the following monomers which are spontaneously hydrophilic or a simple transformation (quaternization of an amine or neutralization of an acid) renders hydrophilic in the polymer structure : ethylenic carboxylic acids such as acrylic acid, methacrylic acid, itaconic acid, fumaric acid, crotonic acid; acrylates and methacrylates of polyethylene glycol or of glycol substituted or unsubstituted on their terminal function by alkyl, phosphate, phosphonate or sulphonate groups; amides of unsaturated carboxylic acids such as acrylamide or methacrylamide and their N-substituted derivatives; aminoalkyl acrylates and methacrylates, aminoalkyl methacrylamides; carboxylic anhydrides carrying a vinyl bond such as maleic anhydride or fumaric anhydride; vinylamides such as vinylpyrrolidone or vinylacetamide; vinyl
- hydrophobic monomers are generally chosen from the following monomers:
- styrenic derivatives such as styrene, alpha-methylstyrene, para-methylstyrene, tert-butylstyrene; vinyl esters, such as vinyl acetate, vinyl propionate, vinyl butyrate, vinyl stearate, vinyl benzoate, vinyl esters of versatic acid, alkyl (meth) acrylates, Ci -C 12 linear or branched; polyethylene glycol (meth) acrylates; acrylonitrile and methacrylonitrile;
- dienes such as butadiene or isoprene
- hydrophobic monomers is meant here monomers which form homopolymers insoluble in water.
- water-soluble as used herein in connection with a polymer means that the polymer is soluble in water at 25 ° C in a mass concentration of at least 0.1%, preferably at least 1%. %, still more preferably at least 5% and most preferably at least 15%.
- the mixture of the monomers to be polymerized, a radical polymerization initiator and a RAFT agent for controlling the polymerization are introduced into a stirred reactor, optionally containing at least one solvent.
- the proportion of hydrophilic monomer (s) and hydrophobic monomer (s) in the starting reaction medium may vary in large proportions, and in general the amount of hydrophilic monomer (s) is included between 5% and 95% by weight relative to the total weight of monomer (s), preferably between 15% and 85%, more preferably between 25% and 75%.
- hydrophilic monomers chosen from acrylic acid, methacrylic acid, sodium styrene sulphonate and polyethylene glycol (meth) acrylates and the hydrophobic monomers chosen from styrene and alpha-methylstyrene are particularly preferably used in the process of the invention.
- hydrophilic monomers (acrylic acid + M 1 ) and hydrophobic monomers (styrene + M 0 ), where M 1 represents a hydrophilic monomer different from acrylic acid and M 0 represents a hydrophobic monomer different from styrene, and in which the proportion (acrylic acid + Mg + styrene + M 0 ) is between 5/95 and 95/5 by weight, preferably between 15/85, more preferably between 25/75. In a preferred embodiment, the proportion (acrylic acid + M ⁇ styrene + M 0) is between 30/70 and 40/60 by weight.
- the amount of M 1 can vary from 0 to 99.9% by weight relative to the sum of the hydrophilic monomers and the amount of M 0 can vary from 0 to 99.9% by weight relative to the sum of the hydrophobic monomers.
- the following monomers are particularly preferred: acrylic acid / styrene, in a proportion of 30/70 to 50/50 by weight; or acrylic acid / styrene / alpha-methylstyrene, in a proportion of 1 AI 1 AI 1 A by weight.
- the mixture of monomer (s), and more generally the reaction medium may be placed under an inert gas atmosphere vis-à-vis the radical polymerization, said inert gas may be for example nitrogen or argon. The presence of inert gas is not necessary, however.
- a solvent for the reaction medium it is preferably a solvent of the starting monomers and advantageously of the copolymer which will be formed.
- the possible solvents mention may be made of water, linear or branched alcohols, glycols such as diethylene glycol, propylene glycol monomethyl ether and dipropylene glycol monomethyl ether, dimethyl sulfoxide, alkyl esters, in particular alkyl acetates, such as inter alia, butyl or ethyl acetates, ketones such as methyl ethyl ketone (MEK), methyl-4-butyl ketone (MIBK), as well as mixtures of two or more of them.
- MEK methyl ethyl ketone
- MIBK methyl-4-butyl ketone
- the method of the invention can therefore advantageously be implemented without the use of solvents considered harmful or toxic to the environment and / or the animal world, and which are commonly used as indicated in the state of the art, such as as dioxane, N-methylpyrrolidone, dimethylformamide, and others.
