Document Type and Number:
WIPO Patent Application WO/2021/082257
Kind Code:
A1
Abstract:
The present invention relates to a physical hydrogel and a preparation method thereof, the physical hydrogel includes the following ingredients calculated by moles, : 1-30 parts of monomer A, monomer A is acrylic acid or methacrylic acid; 1-30 parts of monomer B, monomer B is dimethylaminoethyl acrylate or dimethylaminoethyl methacrylate; 40-98 parts of monomer C, monomer C is alkyl acrylate and the mixture thereof, the alkyl chain is any one of C1 to C30. The main ingredients of the physical hydrogel in the present invention are acrylic acid, dimethylaminoethyl acrylate and alkyl acrylate, which avoids the use of surfactant, and fundamentally improves the stability of the hydrophobically associating physical hydrogel. The method of the invention has simple operation and can realize the large-scale preparation of the hydrophobically associating physical hydrogel.
