    摘要: This disclosure relates to a method for preparing polyalkylenecarbonate. More specifically, in the method for preparing polyalkylenecarbonate, by using a solution polymerization with a specific heterogeneous catalyst and a solvent in the polymerization process of an epoxide compound and carbon dioxide, the products of side-reaction are reduced, removal of metal residues and by-products from the products is facilitated, danger due to overheating of the reactants is minimized, and heat removal and process stability are improved, and thus, high molecular weight copolymer may be easily provided, and mass production and scale-up are easy.

    摘要: Thermosetting resins and thermosetting composites comprising the thermosetting resins are hot-formable. The compositions result from contacting at least one thermosetting resin precursor with at least one hardener selected from acid anhydrides in the presence of at least one transesterification catalyst. The thermosetting resin precursor includes hydroxyl functions and/or epoxy groups, and optionally ester functions, and the total molar quantity of the transesterification catalyst is between 5 and 25% of the total molar quantity of hydroxyl and epoxy contained in the thermosetting resin precursor. Methods for manufacturing articles comprising the thermosetting resins and methods for recycling the thermosetting resins are also disclosed.

    摘要: Composite carboxy terminated polybutadiene (CTPB) rubber base propellants, in which the CTPB inherently contains 2,2'-methylene-bis(4-methyl-6-tert-butyl)phenol (A0-2246) added during CTPB manufacture and antagonistic toward conventional antioxidants added to the CTPB propellant, are provided, which contain a synergistic (see Markush definition) antioxidant mixture highly compatible with the inherently present AO-2246. Invention also provides the antioxidant mixture per se.
