摘要: The present invention relates to a method of preparing RAFT, ATRP or NMRP functionalized thin film composite (TFC) polyamide membranes on a microporous substrate. A further aspect of the invention is the subsequent modification of the thin film composite polyamide membrane by controlled free radical polymerization (CFRP) to yield membranes having new chemical and physical properties, e.g. antifouling and/or antibacterial properties. Further aspects of the invention are the functionalized thin film composite (TFC) polyamide membranes on the microporous substrate itself and the membranes modified by controlled free radical polymerization.

摘要: A method for forming a monomeric carbonate includes the step of combining a monofunctional alcohol or a difunctional diol with an ester-substituted diaryl carbonate to form a reaction mixture. Similarly, a method for forming a monomeric ester includes the step of combining a monofunctional carboxylic acid or ester with an ester-substituted diaryl carbonate to form a reaction mixture. These methods further include the step of allowing the reaction mixtures to react to form a monomeric carbonate or a monomeric ester, respectively.

摘要: The present invention provides methods of forming carbamates, ureas, and isocyanates. In certain embodiments these methods include the step of reacting an amine with an ester-substituted diaryl carbonate to form an activated carbamate which can be further derivatized to form non-activated carbamate or a urea. The urea or carbamate can be subjected to a pyrolysis reaction to form isocyanate.
