Diene polymers and copolymers terminated with compounds having multiple-bonded nitrogen atoms and partially crosslinked with polyfunctional reagents |
摘要 |
Diene polymers or copolymers having improved raw polymer viscosity and reduced hysteresis in the cured and carbon black reinforced state are provided. These diene polymers or copolymers are prepared by a method which involves first terminating substantially all of the living diene polymer or copolymer chains obtained by anionic polymerization with a compound having multiple-bonded nitrogen atoms selected from the group consisting of aromatic nitriles and substituted imines having the formula <IMAGE> and then coupling a portion of the resultant terminated polymer chains with a polyfunctional reagent selected from the groups consisting of silicon polyhalides, polyisocyanates, phosphoryl halides and polycarboxylic acid halides.
