1、1 高分子第二章习题参考答案1下列烯类单体适于何种机理聚合：自由基聚合，阳离子聚合或阴离子聚合？并说明理由。CH2=CHCl，CH2=CCl2，CH2=CHCN，CH2=C（CN）2，CH2=CHCH3，CH2=C（CH3）2，CH2=CHC5H6，CF2=CF2，CH2=C（CN）COOCH3，CH2=C（CH3）CH=CH2参考答案：自由基聚合：CH2=CHCl，CH2=CCl2，CH2=C（CN）2，CH2=CHC5H6，CH2=C（CH3）CH=CH2，CF2=CF2，CH2=C（CN）COOCH。阴离子聚合：CH2=CHCN，CH2=C（CN）2，CH2=CHC5H6，CH2=C（C

2、H3）CH=CH2，CH2=C（CN）COOCH。阳离子聚合：CH2=CHCH3，CH2=CHC5H6，CH2=C（CH3）CH=CH2，CH2=C（CH3）2。CH2=CHCl：适于自由基聚合，Cl 原子是吸电子基团，也有共轭效应，但较弱。CH2=CCl2：适于自由基聚合，Cl 原子是吸电子基团。CH2=CHCN：适于自由基聚合和阴离子聚合，CN 是强吸电子基团，并有共轭效应。CH2=C（CN）2：适于自由基聚合和阴离子聚合，CN 是强吸电子基团。2 CH2=CHCH3：适于阳离子聚合，CH3是供电子基团，CH3是与双键有超共额轭效应。CH2=C（CH3）2：适于阳离子聚合，CH3是供电子基

3、团，CH3是与双键有超共轭效应。CH2=CHC5H6和 CH2=C（CH3）CH=CH2：均可进行自由基聚合、阳离子聚合和阴离子聚合。因为共轭体系电子的容易极化和流动。CF2=CF2：适于自由基聚合。F 原子体积小，结构对称。CH2=C（CN）COOCH：适合阴离子和自由基聚合，两个吸电子基，并兼有共轭效应。2判别下列单体能否进行自由基聚合，并说明理由。CH2=C（C5H6）2，ClCH=CHCl，CH2=C（CH3）C2H5，CH3CH=CHCH3，CH2=C（CH3）COOCH3，CH2=CHOCOCH3，CH3 CH=CHCOCH3参考答案：CH2=C（C5H6）2不能通过自由基聚合形成

4、高分子量聚合物。因为取带基空间阻碍大，形成高分子键时张力也大，故只能形成二聚体。ClCH=CHCl 不能通过自由基聚合形成高分子量聚合物。因为单体结构对称，1，2-而取代基造成较大空间阻碍。CH2=C（CH3）C2H5不能通过自由基聚合形成高分子量聚合物。由于双键电荷密度大不利于自由基进攻。CH3CH=CHCH3不能通过自由基聚合形成高分子量聚合物。因为为阻文档编码:CG3B8Y8M5O1 HU7J2U10I4Y6 ZG3K2Q4A2V10文档编码:CG3B8Y8M5O1 HU7J2U10I4Y6 ZG3K2Q4A2V10文档编码:CG3B8Y8M5O1 HU7J2U10I4Y6 ZG3K2Q

41、U10I4Y6 ZG3K2Q4A2V107 简单自由基在形成稳定分子的同时，只生成一个新的自由基。由于去尝的消耗了一个引发剂分子，故使实际引发效率降低。笼蔽效应是由于初级自由基受溶剂分子包围，限制了自由基的扩散，导致初级自由基的偶合（或歧化）终止，使引发效率降低。11推导自由基聚合动力学方程是，作了哪些基本假设？聚合速率与引发剂浓度平方根成正比，是哪一机理造成的。这一结论的局限性怎样？参考答案：三个假设：（1）等活性理论假设，即链自由基的活性与链长基本无关；（2）稳态状态假设，即引发速率和终止速率相等；（3）用于引发的单体远少于增长消耗的单体，即RiRp。聚合速率与引发剂浓度平方根成正比，是由
