Definitions
- the present invention relates to a process for the preparation of homo-, co- and block copolymers by controlled free-radical polymerization of olefinically unsaturated monomers in aqueous solution.
- the technical production of polymers by means of radical polymerization is a comparatively very inexpensive and technically frequently used process.
- the molecular weight distributions (polydispersities), determined by the quotient of the weight and number average of the molecular weight (M w / M ⁇ ) of the synthesized polymers, are generally high in the conventional processes.
- the radical atom transfer polymerization represents a further method of a radical polymerization.
- ATRP olefinically unsaturated monomers with a catalyst / initiator system consisting of a metal complex such as CuBr * 2 bipyridine as a catalyst and a halogen compound as Initiator polymerizes.
- a catalyst / initiator system consisting of a metal complex such as CuBr * 2 bipyridine as a catalyst and a halogen compound as Initiator polymerizes.
- This methodology is described by Matyjaszewski et al. described.
- Matyjaszewski et al. investigated the controlled "living" radical atom transfer polymerisation of styrene (J. Am.Chem.Soc.
- a disadvantage of this process is the water-insolubility of the metal / ligand catalysts (heavy metal complexes) used for the ATRP polymerization. Therefore, even when using water-soluble monomers, solvent mixtures consisting mainly of organic solvents have to be used in order to obtain a homogeneous reaction solution.
- the metal residue from the catalyst (eg copper) in the polymer is often very high in the ATRP, since the ATRP is often carried out in bulk or in organic solution. Copper halides are harmful to health and also impair the material properties of the polymers.
- the heavy metal complexes used are problematic in several respects. You color the polymers obtained are strong, are difficult to remove and do not allow the use of monomers with free carboxylic acid groups.
- (block co-) polymers with precisely these monomers (acrylic acid, methacrylic acid, maleic acid) are desirable in construction chemical products and formulations, which is why an alternative process would be very advantageous.
- Controlled radical polymerization with scavengers such as N-oxides (nitroxyl radicals) or triazolinyl radicals in aqueous solution, was achieved by adding
- Cyclodextrins improved.
- the problem of the insolubility of the olefinically unsaturated monomers and the radical scavenger in aqueous solution was eliminated (DE-OS 10027744), it being possible to dispense with the addition of emulsifiers.
- Radical atom transfer polymerization (ATRP) in aqueous solution was also improved by the presence of cyclodextrins.
- Olefinically unsaturated monomers and the water-insoluble initiators and metal-ligand compounds could be converted into water-soluble forms and polymerized without the addition of emulsifiers, protective colloids etc. or organic cosolvents by adding cyclodextrins (DE-OS 10027 746).
- cyclodextrins DE-OS 10027 746.
- Copper halides are harmful to health, impair the material properties of the polymer, strongly color the polymers obtained, are difficult to remove and do not allow the use of monomers with free carboxylic acid groups.
- Block copolymerization of water-soluble and / or water-insoluble olefinically unsaturated monomers in the presence of 1,1-diphenylethylene in organic solvents, in water and in bulk (Macromol. Symp. 177. 2002. 25-41).
- the processes described in these applications are all carried out in a strongly alkaline environment in the presence of at least one base.
- the amounts of initiator are up to 50% by weight, based on the monomer component, and the proportion of compound (A) is likewise stated to be up to 50% by weight, based on the monomer component.
- reaction mixture contains 10% by weight or less water and the reaction is carried out at a pressure between 1 and 300 bar.
- the polydispersities of the block copolymers are in the range from 1.5 to 4.2 in the examples given.
- the examples further describe that monomers and compound (A) and the initiator in aqueous solution are metered into the reaction solution separately and in parallel over a certain period of time.
- Initiator radicals or monomer radicals are present and are evenly distributed in the reaction space. All polymer chains are then started simultaneously and each chain adds the same number of monomer molecules in the case of irreversible growth steps, as a result of which there is practically no distribution of the degree of polymerization.
- the present invention was therefore based on the object of a method to provide for the production of homo-, co- and block copolymers by controlled radical polymerization in aqueous solution, which at least partially overcomes the disadvantages of the prior art and enables a controlled and environmentally friendly production of the corresponding polymers without the addition of emulsifiers, protective colloids or organic cokes ,
