摘要
2，3－二甲基－2，3－二苯基丁烷，由于其结构上的特殊性，在一定条件下易形成稳定性较高的自由基，可作为一种自由基引发剂用于聚合物的交联共聚，达到改善聚合物性能的目的。对于烯烃类聚合物可用作阻燃剂的增效剂，降低卤素类阻燃剂的用量及对聚合物性能的影响，提高聚合物的防火阻燃效果。与常见自由基引发剂相比较，使用安全是它的又一特性。
2, 3 - dimethy1 - 2, 3 - diphenylbutane can form stable free radical easily due to its special property in structure. It can usually be used as a free - radical initiator in crosslinking copolymerizaion of polymrs. Whereas, it also can be used as synergist for fire proofing agent for polydefins to decrease its influence on the properties of polymers and the dose of it. Thus the fire - proofing effect of polymers will be improved greatly. Compared with common free - radical initiator, it is safe in use.
