  Paramagnetic, amphiphilic, biocompatible polymers were prepared comprising a carbonate repeat unit bearing a paramagnetic organic radical, more specifically a nitroxyl radical. The radical polymers can be produced in one step from a precursor polymer bearing an active ester side chain by treating the precursor polymer with a radical-bearing nucleophile. The precursor polymer can be prepared by organocatalyzed catalyzed ring opening polymerization (ROP) of a cyclic carbonate monomer bearing an active ester side chain. The radical polymers can be non-toxic and partially biodegradable. The radical polymers have utility as contrast enhancing agents in a medical imaging application and/or as therapeutic agents for treating a medical condition. The radical polymers can also serve as carriers for therapeutic agents (e.g., drugs) and/or medical image enhancing agents (e.g., NIRF dyes).

  具有顺磁性、两性亲疏性、生物相容性的聚合物已经制备好，其中包含一个带有顺磁性有机自由基的碳酸酯重复单元，更具体地说是一个亚硝基自由基。这种自由基聚合物可以通过将带有活性酯侧链的前体聚合物与带有自由基的亲核试剂处理而一步制备而成。前体聚合物可以通过有机催化的环氧化聚合（ROP）来制备，该环氧化单体带有活性酯侧链。这种自由基聚合物可能是无毒且部分可生物降解的。这种自由基聚合物在医学成像应用中可用作增强对比剂，和/或作为治疗医疗状况的治疗剂。这种自由基聚合物还可以作为治疗剂（例如药物）和/或医学图像增强剂（例如NIRF染料）的载体。

  A method is disclosed for preventing the polymerization of (meth)acrylic acid and esters thereof, which method is characterized by using an N-nitrosophenyl hydroxyl amine or a salt thereof, an N-oxyl compound, an N-hydroxy-2,2,6,6-tetramethylpiperidine compound, and a 2,2,6,6-tetramethylpiperidine compound in combination in a purifying column. The N-nitrosophenylhydroxylamine or the salt thereof is partly decomposed in the purifying column and is allowed to ascend the interior of the column and effectively inhibit the polymerization of (meth)acrylic acid. Since the method does not need to use any metal compound, it permits the disposal of the waste liquid to be effected easily. Further, the combined use of the relevant components ensures effective prevention of the polymerization in the gas and the liquid phase.

  本发明公开了一种防止(甲基)丙烯酸及其酯类聚合的方法，其特征在于将 N-亚硝基苯基羟胺或其盐、N-氧代化合物、N-羟基-2,2,6,6-四甲基哌啶化合物和 2,2,6,6-四甲基哌啶化合物组合使用在净化柱中。N-亚硝基苯基羟胺或其盐在净化柱中部分分解，并进入净化柱内部，从而有效抑制（甲基）丙烯酸的聚合。由于该方法不需要使用任何金属化合物，因此废液的处理非常容易。此外，联合使用相关成分可确保有效防止气相和液相中的聚合。

  A graft copolymer having a structure in which a vinyl copolymer segment formed from a vinyl monomer having an acid is suspended in a molecular chain of a polyolefin resin segment via a β-substituted propylene group is obtained, by reaction of polyolefin resin having β-substituted propenyl group as a pendant and a vinyl monomer having an acid, and further a graft copolymer composition containing the same and a molded product thereof are obtained. The obtained graft copolymer, the composition containing the same and the molded product thereof are excellent in adhesive property to a polar material and scratch resistance.

  一种接枝共聚物，其结构是将具有酸性的乙烯基单体形成的乙烯基共聚物段通过β-取代的丙烯基团悬浮在聚烯烃树脂段的分子链中，它是通过具有β-取代的丙烯基团作为悬垂基的聚烯烃树脂和具有酸性的乙烯基单体反应而获得的，并进一步获得含有该接枝共聚物的接枝共聚物组合物及其模塑产品。所获得的接枝共聚物、含有相同成分的组合物及其模塑产品在与极性材料的粘合性和抗划伤性方面都非常出色。
