【摘要】 BDC引发苯乙烯的均相聚合反应是以活性自由基机理进行的;大分子自由基间的偶合反应及向大分子的链转移反应使聚合产物不带有活性端基;大分子链活性端基数的测定结果表明了这种失活性的存在。更多还原

【Abstract】 The homogenous polymerization of styrene initiated by BDC (N, N—diethyldithiocarbamate benzyl)proceeded in living radical polynlerization mechanism. The intercoupling of macromolecular radicals and the chain transferring to macromolecules made the polymers lack reactive end groups. This was vertified by determination of the end group number in every polymer molecule.更多还原
