    • Improved processes have been developed for atom (or group) transfer radical polymerization (ATRP). In one improvement, the ATRP process involves polymerizing in the presence of a (partially) free radical-deactivating amount of the corresponding reduced or oxidized transition metal compound. In a further improvement, the ATRP process involves polymerizing in a homogeneous system or in the presence of a solubilized initiating/catalytic system. The present invention also concerns end-functional, site-specific functional and telechelic homopolymers and copolymers; block, random, graft, alternating and tapered (or “gradient”) copolymers which may have certain properties or a certain novel structure; star, comb and “hyperbranched” polymers and copolymers; multi-functional hyperbranched, end-functional polymers; cross-linked polymers and gels; water-soluble polymers and hydrogels (e.g., a copolymer prepared by radical copolymerization of a water-soluble monomer and a divinyl monomer); and an ATRP process using water as a medium.
    • 已经开发了用于原子(或基团)转移自由基聚合(ATRP)的改进方法。 在一个改进中,ATRP方法包括在(部分)游离基失活量的相应还原或氧化的过渡金属化合物的存在下聚合。 在进一步的改进中,ATRP方法包括在均相体系中或在溶解的引发/催化体系存在下进行聚合。 本发明还涉及终端功能,位点特异性功能和遥爪均聚物和共聚物; 嵌段,随机,接枝,交替和渐缩​​(或“梯度”)共聚物,其可以具有某些性质或某种新颖结构; 星形,梳状和“超支化”聚合物和共聚物; 多功能超支化,末端官能聚合物; 交联聚合物和凝胶; 水溶性聚合物和水凝胶(例如,通过水溶性单体和二乙烯基单体的自由基共聚制备的共聚物); 和使用水作为介质的ATRP方法。
