Page/Page column 7, (2009/03/07)
The present invention provides an adhesive composition comprising a polymerizable phosphonic acid derivative which is a composition having intramolecularly a polymerizable group and a phosphonic acid group, represented by the general formula [1]: wherein R represents a polymerizable group;A represents an oxygen atom or a sulfur atom;Xqs represent independently an oxygen atom or a sulfur atom;Yqs represent independently the same or different organic group;Zqs may be independently the same or different from each other and, a part of the Zqs optionally selected or all of the Zqs represent organic groups having a substituent which is an organic group other than a polymerizable group and a phosphonic acid group;p is an integer from 1 to 10;q is an integer from 1 to p; when p is 1, q is 1;X1 represents an oxygen atom or a sulfur atom;Y1 represents an organic group;Z1 represents an organic group having one or more of substituents which are organic groups other than an acidic group and a polymerizable group, or a salt thereof. The adhesive composition or the salt thereof according to the present invention improve a shelf life and adhesion properties of an adhesive composition comprising essentially a (meth)acrylate monomer having intramolecularly an acidic group and water in dental treatment.

A range of α-amino-, ω-amino-, α-guanidino-, and ω-guanidinoalkanephosphonic acids has been prepared for the purpose of studying their spectroscopic features and fungicidal activity.In addition, α-thioureido-octanephosphonic acid and thioureylene-1,1-bis(1-octanephosphonic acid) were isolated during the preparation of α-guanidino-octanephosphonic acid. 31P, 1H, and 13C nmr spectral data which were obtained for solutions of the amino- and guanidino-compounds in D2O or D2O/D2SO4, and for the thioureido compounds in DMSO-d6, are discussed together with previouslyreported data for the aminophosphonic types.FAB mass spectrometry generally gives strong pseudomolecular ions + for the zwitterionic amino- and guanidino-compounds with relatively simple fragmentations.Fungicidal activity of the α-aminophosphonic acids was found to be greater than for the ω-amino compounds, with maximum activity at a chain length of three carbon atoms when used as a seed dressing for the control of Drechslera spp.Moderately good activity was shown by the thioureido compounds against a number of fungal organisms in vitro but the guanidino-compounds exhibited low activity.Key words: Organophosphorus; fungicides; aminophosphonic acids; guanidinophosphonic acids; NMR spectroscopy; FAB mass spectroscopy.
