  • Patent number: 9109092
    Abstract: Disclosed is a method for preparing a semi-furanic copolyamide containing at least one furanic dicarboxylic acid moiety and at least one aliphatic diamine moiety in the backbone. The method is based on solid-state polymerization. Particularly, the method uses a biomass-derived furanic dicarboxylic acid as a raw material. A semi-furanic copolyamide prepared by the method has molecular weight and color levels that are practically required in industrial applications. In addition, the semi-furanic copolyamide can replace fossil fuels due to its good thermal stability and is suitable for use as an environmentally friendly bioplastic.

  • Patent number: 9044515
    Abstract: The present invention is related to compositions which can undergo targeted degradation under certain physiological reducing conditions. The compositions may, for example, be hydrogels in which maleimide-functionalized low molecular weight heparin is cross-linked with various thiol-functionalized polyethylene glycol multi-arm star polymers. Both the gelation and degradation of the hydrogels can be modified by careful selection of the thiol. For example, hydrogels prepared from aryl thiol-maleimide adducts can undergo a retro Michael addition-type reaction, leading to degradation of the composition and release of the bioactive molecule.

  • Patent number: 9006381
    Abstract: Provided are: an impact-resistant polyamide composition which exhibits improved toughness and improved impact strength and which can be easily polymerized in-situ in a molding stage; and a novel process for the production of the same. The novel process comprises initiating the anionic polymerization of ?-caprolactam in the presence of (A) an anionic polymerization catalyst, (B) an anionic polymerization activator, (C) 2.0 to 30% by weight (relative to the ?-caprolactam) of an N,N-disubstituted vinylbenzylamine, and (D) a radical polymerization initiator, and subjecting the resulting system to reaction under conditions comprising a reaction temperature of the reaction system of 120 to 180° C. and a reaction time of 10 seconds to 120 minutes. Since radical polymerization in the process is conducted without hindering the anionic polymerization, an alloyed polyamide composed of both polycaprolactam and poly (N,N-disubstituted vinylbenzylamine) can be obtained.
