Abstract: Particulate, Free-Flowing, Insoluble Swellable Polymers are provided which are comprised of a mixture of an insoluble, swellable hydrogel and inert filler. The mixtures are freeflowing powders or granules which can absorb many times their weight of water and hence are useful as a soil amendment.
Abstract translation: 提供颗粒状,自由流动的不溶性可溶胀聚合物,其由不溶性,可溶胀水凝胶和惰性填料的混合物组成。 混合物是自由流动的粉末或颗粒,其可以吸收其重量的许多倍,因此可用作土壤修饰物。
