Definitions
- the present invention relates to water-soluble heat-sensitive copolymers based on (meth) acrylate.
- the present invention relates to water-soluble thermosensitive copolymers, which can be used for the manufacture of disposable hygiene articles in toilets because of their capacity to form films capable of breaking down or rapidly disintegrating in an aqueous medium.
- the copolymers of the invention which can also be used, as components of disposable or water-disintegrable hygiene articles: (1) as a binder connecting the fibers of the fibrous (nonwoven) sheets which form the upper envelope of the article; or
- thermosensitive or thermosensitive copolymers is understood to mean copolymers which are soluble in water below a certain critical temperature commonly called LCST, but which become insoluble in water at temperatures higher than LCST. . So, for example, the movies prepared from these copolymers are said to be “water-disintegrable” or “water-dispersible”.
- copolymers must be easily dispersible in water (5-20 ° C.) with stirring in order to be able to be eliminated by a flushing effect without clogging the pipes, but that at human body temperature (37 ° C), they must be insoluble in water and body fluids to guarantee the integrity of these items during their use.
- the composition of the polymers must be able to be adjusted so that they have an LCST which is both lower than the temperature of the human body (37 ° C) and higher than the temperature of the toilet water. (5-20 ° C), so as to guarantee, on the one hand, the non-solubility in water at 37 ° C and good dispersibility or solubility in water at 5-20 ° C.
- one of the approaches consists in formulating the binder which must connect the fibers of the nonwoven, so that it causes the disintegration of the fibrous web in an aqueous medium.
- water-dispersible adhesives connecting the various components of the hygiene article are proposed in American patents US-A-4,522,967 and US-A-5,527,845.
- thermosensitive products having a significant difference in solubility at the critical LCST temperature and in particular a significant difference in solubility between the temperature of the human body 37 ° C and that of toilet water 5- 20 ° C;
- hydroxypropylcellulose (LCST ⁇ 44 ° C) and methylated hydroxypropylcellulose whose hydrophobic modification by methylation of hydroxypropylcellulose makes it possible to reduce the LCST in the range of 19-35 ° C
- PVME polyvinyl methyl ether

- new compositions of heat-sensitive copolymers which meet these criteria by providing access to a wide range of LCSTs which can vary between 6 and 95 ° C, including the range 20 to 35 ° C for the particular application envisaged.
- the adjustment of the LCST in this temperature range is possible by varying parameters such as the transfer agent, the nature and the rate of the monomers used for the copolymerization, the synthesis temperature, the mode of introduction of the monomers. (batch or semi-continuous), the molar masses of the copolymers.
- the low LCST values (approximately 20 to 24 ° C.) can be obtained by varying the number of alkylene oxide units present, as well as the composition and the transfer agent, and the adjustment of the LCST at low temperatures (20-24 ° C) allows rapid soluble / insoluble transition kinetics at skin temperature (37 ° C) unlike higher LCST systems (PVME and poly-NIPAM).
- the hydrophobic units are directly incorporated into the structure of the new water-soluble heat-sensitive copolymers of the present invention.
- These new heat-sensitive polymers make it possible to prepare water-dispersible films. They can also be used with hydrophobic polymers in proportions which preserve the water disintegrability of the films of the formulated product. They can also be used for the formulation of binders for fibrous webs as well as for water-dispersible adhesives for the manufacture of water-disintegrable hygiene articles.
