| Abstract: | A series of modified polyurethane preoligomers with different amino siloxane content were synthesized without the presence of organic solvent. The silicon modified polyurethane elastomer materials which were used as high performance chemical materials for construction were synthesized with the preoligomers and dimethylsulfide toluylenediamine. The properties of the materials were investigated by using stress-strain analysis, heat- resistance analysis, surface water contact angle, water- resistance analysis and acid(alkali)-resistance analysis. The result show the modified materials have excellent synthetical properties. |
