Definitions
- the present invention relates to an original polymerization process giving access to water-soluble polymers of very high mass, typically of the order of 100 000 to 1 000000 g / mol, and with a control of the mass of these polymers.
- the invention also relates to the water-soluble polymers of high controlled mass thus obtained, which can be used in particular as rheological agents, surface modifiers and flocculating agents.
- a "physical gel” refers to a non-covalent gel of the aforementioned type, excluding chemically cross-linked structure, resin type for example.
- these physical gels such as obtained according to the gel polymerization processes, are distinguished from the so-called “nanogel” or “microgel” structures described for example in WO 2010/046342 or WO 2008/155282 and which comprise red blood cells.
- a chemically crosslinked phase (improperly described as "gelled") within a dispersing medium.
- the rapid gelation of the medium generates a very high exotherm, which implies in particular the implementation of specific initiator systems.
- gel polymerization processes are not able to provide control of the size and architecture of the polymer chains formed.
- the gel polymerization does not make it possible to access block polymers (for example diblocks).
- RAFT RAFT
- MADIX reversible addition-fragmentation transfer method
- control agents also known as reversible transfer agents
- controlled radical polymerization processes lead, in a well-known manner, to the formation of polymer chains, all of which grow substantially at the same rate, which results in a substantially linear increase in the molecular weights with the conversion and a narrow mass distribution.
- a number of chains which typically remains substantially fixed throughout the duration of the reaction, which makes it possible very easily to control the average molar mass of the polymer synthesized (this mass is even higher than the initial concentration of control agent is low, this concentration dictates the number of growing polymer chains).
- the controlled polymerization processes of acrylamide disclosed to date result in polymers of relatively limited size.
- the examples of controlled radical polymerizations of acrylamide leading to the polymers of the highest sizes mention may be made of: a RAFT polymerization of redox-primed acrylamide at room temperature, described in Macromolecular Rapid Communications, vol. 29, No. 7, pp. 562-566 (2008), which leads to polyacrylamides having a molar mass in number M n of at most 40,000 g / mol; and
- An object of the present invention is to provide a method for obtaining both hydrophilic polymers of very high molar mass, well above 100,000 g / mol, preferably at least 500,000 g / mol, while providing a control of the mass of the polymers, with a substantially linear increase in molecular weights with the conversion and a mass distribution tightened around a mean value.
- the present invention provides a novel type of hydrophilic polymer synthesis method, which combines the specificities of gel polymerization and controlled radical polymerization. Against all odds, it turns out that this new type of process can combine the benefits of each of the two methods without retaining the harmful aspects.
- the present invention provides a process for the preparation of a polymer comprising at least one gel polymerization step (E) in which, generally in an aqueous medium:
- a source of free radicals adapted to the polymerization of said monomers typically a redox system

- step (E) it is in fact possible to control the number-average molar mass of the polymers to very high values, which allows the synthesis of polymers and copolymers with controlled architecture with less a hydrophilic sequence of both high mass and controlled mass.
- step (E) leads to the synthesis of polymers whose molar mass in number M n is controllable by varying the initial concentration of control agent in the medium, the value of M n being even higher than this initial concentration of control agent is low.
- step (E) can typically lead to the synthesis of a hydrophilic polymer block having a molecular weight Mn greater than 500,000 g / mol, for example between 500,000 and 1,000,000 g / mol.
- step (E) effective control of the average mass of the polymers, of a type similar to that obtained with conventional controlled radical polymerization processes, is obtained, with the difference that this control effective to very high sizes (up to 1,000,000 g / mol or more)
- the initial concentration of control agent in the medium is chosen such that the synthesized hydrophilic polymer block average molecular weight has a number-average molecular weight Mn greater than 100,000 g / mol, preferably greater than or equal to 500,000 g / mol, for example between 500,000 and 1,000,000 g / mol.

In some cases, the system gels during the polymerization, but it may remain more fluid in other cases. In all cases, step (E) allows a polymerization of controlled type, unlike the conventional type of gel polymerization, conducted without additional control agent.

- the theoretical average molecular weight is 900,000 g / mol
- EXAMPLE 11 Synthesis of a diblock copolymer poly (acrylamidopropyltrimethylammonium chloride) -b-poly (acrylamide) - Synthesis of the poly (acrylamide) block according to the invention (control agent: xanthate-terminated living polymer - initiator: persulfate couple ammonium / sodium formaldehyde sulfoxylate)
- Step 1 Synthesis of the poly (acrylamidopropyltrimethylammonium chloride) block
- Example 8 The same polymer formed in Example 8 is used.
- Example 10 The same polymer P10 as that of Example 10 was used in this example, used in the form of a powder prepared under the conditions of Step 10.2 of Example 10.
- the polymerization reaction was then allowed to proceed with stirring for 24 hours at room temperature (20 ° C.). At the end of the 24 hours of reaction, a conversion of 98% was obtained, as determined by 1 H NMR.
