DESCRIPTION:
BRIEF SUMMARY
The present invention relates to novel functionalised polymers, method for synthesising same and uses thereof as surfactants, especially as wetting agents and/or dispersing agents and/or stabilising agents of dispersions of solid particles, and for preparing microdispersions.
Chain end-functionalised polymers are already known and, more particularly, functionalised polymers obtained by polymerisation in the presence of a chain transfer agent.
More particularly, work in this field by Y. YAMASHITA, Y. CHUJO and al. will be cited. The authors have essentially described the synthesis of methyl polymethacrylates (PMMA) having --OH or --COOH end groups obtained by using thiomalic acid as chain transfer agent, together with their use in the preparation of macromonomers and as macromonomers for polycondensations.
These pieces of work are stated in "Telechelic Polymers Synthesis and Applications" E. J. GOETHALS, CRC Press Inc. (1989) 169-179.
Macromonomers of general formula (PMMA) SCH(COOH)CH.sub.2 COOH, as well as other acrylic macromonomers having the same end function, are described by Y. YAMASHITA, Y. CHUJO, H. KOBAYASHI and KAWAKAMI in Polym. Bull., 5, 361-366 (1981). All these macromonomers are intended for use in polycondensation operations.
Macromonomers which are also intended for polycondensation operations are described by Y. CHUJO, H. KOBAYASHI and Y. YAMASHITA in J. of Polym. Sci., Part A: Polym. Chem., 27, 2007-2014 (1989), these macromonomers being constituted of a polymer PMMA chain with a dicarboxylic aromatic functional end group.
In all these documents, the functionalised macromonomers are used as reaction intermediate products in the preparation of other macromonomers, or directly as macromonomers for carrying out polycondensation or coupling reactions.
U.S. Pat. No. 3,689,593 describes graft copolymers in which the grafts are constituted of macromonomers with an OH, COOH or NH.sub.2 end group, with which a diisocyanate, and then a functional vinylic monomer have reacted. These polymers are useful as filmogenic agents in compositions such as paints.
Other macromonomers in which the functional group is linked to the polymer group by an isocyanate group have been described particularly for their application in the dispersion and stabilisation of pigments. The following references shall most particularly be cited:
The compounds described in the various documents above are constituted of various types of polymer chains functionalised with various end groups. All these macromonomers are obtained by functionalising a polymer chain with, for example, an --OH group with which a triisocyanate then reacts. A polymer chain is thus obtained which has two isocyanate end groups with which thiomalic acid may then be grafted. The dispersions carried out by the intermediate of these compounds are extremely resistant to flocculation, giving paintings in which they are incorporated increased covering capacity, brightness as well as improved resistance to loss of brightness. Moreover, the proportion of pigments may be increased in keeping the same degree of fluidity as with conventional dispersing agents. However, these products contain isocyanates which can prove to be a nuisance in a cosmetic formulation if there are residual isocyanate functions.
Polymers functionalised at their chain ends with an amino acid have been described by Candan Erbil, Bahattin Soydan, A. Zehra Aroguz and A. Segai Sara.cedilla. in Angewandte Makromolekulare Chemie 213, (1993), 55-63, (Nr 3693).
These polymers are obtained by radical polymerisation of acrylamide in an acid medium initiated by cerium sulphate in the presence of an .alpha.-amino acid. The pieces of work described in this publication result from older pieces of work described in the publications below: 393-401 (1959) (1968) 44, 877-881 (1992)
Hence, the process described in Candan Erbil, Bahattin Soydan, A. Zehra Aroguz and A. Segai Sara.cedilla. in Angewandte Makromolekulare Chemie 213, (1993), 55-63, necessitates the use of concentrated solutions of acid (sulphuric acid,
