The present disclosure relates to a super absorbent polymer, and a preparation method thereof. More specifically, it relates to a super absorbent polymer prepared such that agglomeration between pulverized particles is suppressed, and drying efficiency and uniformity of particle size distribution are improved by including a carboxylic acid-based additive having a specific structure and hydrophobic particles before drying the hydrogel polymer, and a preparation method thereof.

Super absorbent polymer and preparation method thereof

The present disclosure relates to a polymer film, a preparation method of the same, and a polymer film laminate. Specifically, it relates to a new type of polymer film, which is thin and exhibits excellent absorption performance while having excellent flexibility and mechanical properties. In addition, the polymer film is free from scattering or leaking, and does not require an auxiliary substance such as pulp, so that products can be made thinner and the manufacturing process and costs may be reduced. In addition, the present disclosure also relates to a preparation method of the above-described polymer film, and a polymer film laminate including the new type of polymer film.
