High molecular weight poly-biphenoxyphosphazene copolymers with cyclic secondary amino groups
The reaction of poly(dichlorophosphazene) [NPCl2](n), with 2,2′-dihydroxybiphenyl, 2,2′-(OH)C6H4-C6H4(OH), and then with p-anisidine, p-NH2C6H4OMe, in the presence of K2CO3 led to the formation of the chlorine containing phosphazene copolymer {[Np(O2C12H8)](0.75)[NP(NHC6H4OMe)(2)](0.15)[NP(NHC6H4OMe)Cl](0.05)[NPCl2](0.05)}(n), (1), which could be isolated and fully characterised. When using cyclic secondary amines instead of aromatic primary amines, namely, HNC5H10 (piperidine), HNC4H8O (morpholine), HNC4H8S (thiomorpholine), the reaction gave the functionalized copolymers {[NP(O2C12H8)(10.6)[NP(NC5-H-10)(2)](0.35), (2) IINP(O2Cl2H8)](0.65)[NP(NC4H8O)(2)](0.35)}(n), (3) and {[NP(O2Cl2H8)](0.75)[NP(NC4H8S)(2)](0.25)}(n), (4), respectively. The broad bands in their P-31 NMR spectra and the bimodal aspect of their GPC chromatograms suggested they could be forming aggregates in solution. (c) 2006 Elsevier Ltd. All rights reserved.
The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research. I hope my blog about 101-20-2 is helpful to your research. SDS of cas: 101-20-2.
