    摘要: Rigid polyurethane foam and laminate articles comprising a facing material and the said polyurethane foam are prepared by contacting under reaction conditions a urethane-modified polyisocyanate with a polyahl in the presence of a blowing agent comprising water. The urethane-modified polyisocyanate has an isocyanate content of from about 10 to about 29 weight percent and is obtained by reacting a polymethylene polyphenylisocyanate with a polyether polyol having a molecular weight of at least 2000 and an oxyethylene content of at least 35 weight percent. Use of this polyisocyanate provides for enhanced adhesion of the resulting foam, especialIy when it is an all-water blown foam, to facing materials such as metal.

    摘要: The present invention is directed to temperature modulated refractive index measurement. In accordance with the invention a method for determination of the complex temperature coefficient of the refractive index of a sample is provided, wherein the determination of the complex temperature coefficient of the refractive index of the sample is based on a refractive index measurement. Furthermore, the refractive index of the sample is measured over a period of time, wherein the temperature of the sample is modulated over said period of time and the complex temperature coefficient of the refractive index is calculated on the basis of the refractive index measurement over the period of time and the temperature modulation over the period of time. Additionally, a measurement system, in particular comprising a temperature control system and a processing system to carry out the above method, is disclosed.
