Definitions
- the present invention relates to the field of polymeric additives based on styrenic and anhydride units, consisting of macromolecular chains grafted with nitrogenous heterocycle type molecules.
- it also relates to compositions comprising such additives and their uses, in particular in the field of stationery.
- Polymers comprising units derived from styrene or a styrenic derivative and units derived from an anhydride, in particular maleic anhydride, are called SMAs.
- SMA copolymers The use of SMA copolymers is well known in papermaking.
- the polymeric additives based on styrenic and anhydride units make it possible to improve the properties of the paper such as its hydrophobicity, its resistance to water, its printability, its surface appearance.
- These additives are often used as ingredients in liquid compositions for sizing or coating paper, whose rheology can also be favorably modified by helping to reduce the viscosity, especially at high shear or by helping to increase the concentration of of pigments.
- These liquid compositions used to treat the paper during its manufacture are aqueous suspensions of fillers or pigments which may also contain a binder and other additives.
- WO 02/48459 discloses polymers derived from the polymerization of styrene and maleic anhydride used in the formulation of compositions used for coating paper in high speed processes.
- copolymers based on styrenic and anhydride units do not make it possible to meet certain problems encountered in the manufacture of paper in particular.
- the polymeric additive according to the invention is a graft copolymer derived from grafting:

- the molecules (I) and the copolymer (II) can be dissolved in a suitable solvent, such as chloroform, by choosing the reaction temperature so that the reaction occurs within a reasonable time ranging from a few minutes to a few hours.

- the additive is an ingredient of liquid compositions applied in or on paper. These compositions can be used in gluing or coating paper. They can also be used as part of the paper finishing process, for example to coat paper sheets to facilitate subsequent printing on the paper.
- This additive improves the characteristics of the coated paper in terms of printability, color rendering, resolution, mechanical strength and touch.
- An interesting compromise is obtained between the strength and flexibility of the coated coated paper with a coating additive with the additive according to the invention and a good adhesion of one or more coating layers on the paper.
