| 聚氨酯，是在大分子主链中含有氨基甲酸酯基的聚合物称为聚氨基甲酸酯，简称聚氨酯。聚氨酯分为聚酯型聚氨酯和聚醚型聚氨酯两大类。聚酯型是以二异氰酸酯和端羟基聚酯为原料制备的聚氨酯。聚醚型聚氨酯是以二异氰酸酯和端羟基聚醚为原料制备的聚氨酯。 Polyurethane is a polymer containing carbamate group in the main chain of macromolecule. It is called polyurethane, or polyurethane for short. Polyurethane can be divided into polyester polyurethane and polyether polyurethane. Polyester type polyurethane is prepared from diisocyanate and hydroxyl-terminated polyester. Polyether polyurethane is a polyurethane prepared from diisocyanate and hydroxyl-terminated polyether. |
