  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).

  The present invention relates to a process for producing acrolein by liquid phase dehydration of glycerol by preparing a mixture of a catalyst suspended in an organic solvent comprising one or more vinyl polymers and glycerol; and then mixing and heating the mixture to between 150° C. and 350° C. to dehydrate the glycerol and form acrolein. The vinyl polymers are selected from the group consisting of polyolefins, polystyrene, and mixtures thereof. The polyolefins may be polyethylene, polypropylene, polybutylene, polyisobutylene, polyisoprene, polypentene, or mixtures thereof. The acrolein may be subjected to vapor phase oxidation in the presence of a catalyst, such as a mixed metal oxide, to produce acrylic acid.

  本发明涉及一种通过制备悬浮在有机溶剂中的催化剂与甘油混合物，然后将混合物混合加热至150°C至350°C以脱水甘油并形成丙烯醛的液相脱水制备丙烯醛的方法。所述乙烯聚合物选自聚烯烃、聚苯乙烯及其混合物的群组。聚烯烃可以是聚乙烯、聚丙烯、聚丁烯、聚异丁烯、聚异戊二烯、聚戊烯或其混合物。丙烯醛可以在存在催化剂的情况下进行蒸汽相氧化，例如混合金属氧化物，以生产丙烯酸。
