The composition of this siloxane precursor high in amino groups, including the content of reactive groups, can be determined by suitable methods, such as titration, NMR spectroscopy or FTIR spectroscopy.
反応基を含むアミノ基を大量に含むこのシロキサン前駆体の組成は、滴定、ＮＭＲ分光法又はＦＴＩＲ分光法等の好適な方法により決定できる。
The preparation of the desired aminosiloxanes can be monitored by suitable methods, such as NMR spectroscopy or FTIR spectroscopy, and is concluded when a content of reactive groups which lies within the scope according to the invention is determined.
所望のアミノシロキサン類の調製は、ＮＭＲ分光法又はＦＴＩＲ分光法等の好適な方法によりモニターすることができ、そして本発明の範囲に含まれる反応基の含有量を求めることができる。
is essentially free from carboxy， which should be interpreted in such a way that when performing a FTIR analysis of the compound no significant absorption peak is observed at frequencies of from 1705 to 1715 cm-1 where the carboxy groups absorb
本質的にカルボキシを含まず、このことは、化合物のFTIR分析を行って、カルボキシ基が吸収する１７０５から７１５ｃｍ−１の波長を観測しないことで説明できる
