| Abstract: | The preparation of water swelling polyurethane sealants was introduced in the paper. There are two compositions in the sealants: Part A was made from water soluble polyurethane prepolymer, Part B was made from mixures of curing agents?fillers and plastifiers. The sealant had water swelling specific property. The influence of fillers amount, plastifier amount and curing agents forms on sealants' properties are discussed. |
