Poly(NIPAAm) has a low critical solution temperatureof about 33 °C, but in case of the binary grafting the LCST shift tothe lower temperature; probably due to the formation of hydrogenbonds between dimethylamino and acrylic acid groups 2006 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47550101 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.1 Vol.50 |
