It is done by doing. In this case, the poly (N-vinylcarboxylic acid amide) (crosslinked) polymer used is obtained by polymerizing the monomer represented by the general formula (1).

As the monomer represented by the general formula (1),

The amount of the monomer represented by the general formula (2) is preferably 50% by weight or less based on all monomers. If the amount of the monomer represented by the general formula (2) exceeds 50% by weight, it is not preferable because the terpene compound has an increased viscosity and a reduced liquid absorbing ability.

Range. If the amount of the crosslinking agent used is less than 0.005% by weight, crosslinking is not sufficient, and if it exceeds 10% by weight, the crosslinking density becomes too high and the absorption amount of the terpene compound is undesirably reduced.

The poly (N-vinylcarboxylic acid amide) (crosslinked) polymer according to the present invention can be produced by a general polymerization method. For example, aqueous solution polymerization in which a monomer component is dissolved in water and polymerized as it is, reverse phase suspension polymerization in which an aqueous solution of a monomer component is dispersed in an organic solvent, and polymerization in which the monomer component is dissolved but obtained The union can be produced by dispersion precipitation polymerization (slurry polymerization) in which a monomer component is uniformly dissolved in an insoluble organic solvent to carry out polymerization, and in some cases, water, methanol, ethanol or other monomer.

%, Preferably 3 to 15% by weight. When the addition amount is less than 0.1% by weight, the effect of thickening or gelling is low, and when the addition amount is more than 20% by weight, it becomes difficult to uniformly increase the viscosity of the terpene compound or the gel after liquid absorption.
