| titleOfInvention | A kind of casting type nylon/polyester elastomer and preparation method thereof |
| abstract | Present invention offer is a kind of to obtain the technology of preparing of casting type nylon/polyester elastomer by cyclic butylene terephthalate and lactam monomers by anionic ring-opening polymerization.It comprises the following steps：It carries out under the conditions of 110 ~ 120 DEG C vacuumizing water removal first by lactam monomers, cyclic butylene terephthalate and catalyst system and catalyzing, is then warming up to 180 ~ 200 DEG C of progress anionic ring-opening polymerizations again, you can obtain casting type nylon/polyester elastomer.With conventional polyether modified cast nylon elastomer phase ratio, nylon/polyester elastomer prepared by this method has the characteristics that preparation process is simple, mechanical strength and impact flexibility are all good, shrinking percentage is low and good stability of the dimension, has broad application prospects in terms of the structure stress part of engineering machinery, heavy-duty car and field of track traffic. |
