| Abstract: |
| A dynamically-curable thermoplastic elastomer of NBR/PP blend was prepared with a block copolymer formed in the reaction of maleic anhydride-graft polypropylene (MP)/a amine/liquid carboxyl terminal butadiene nitrile rubber (CTBN) as compatibilizer.Among amines, hexamethylene diamine was the most efficient. The preferrable level of the compatibilizer was about 6% . The lower the melt index, the better the properties of the blend. A blend with better properties could be obtained by adding phenolic resin 2402/tin bichloride (8/0.5) curative and a certain level of dioctyl phthalate plasticizer and HAF reinforcing agent. |
