Abstract:
PROBLEM TO BE SOLVED: To provide a method for easily acquiring quantitative information for describing hair characteristics. SOLUTION: The method for acquiring hair characteristic data includes an image acquiring process and a data acquiring process. The image acquiring process is for acquiring a cross-sectional image of hair 50 in which a plurality of fibrous tissues (ortho cells 52a and para cells 52b) composing cortex cells 52 contained in human hair 50 are visualized discriminably from each other. The data acquiring process is for acquiring, from the cross-sectional image, numerical information indicating the distributed state of the plurality of visualized fibrous tissues (ortho cells 52a and para cells 52b).

Abstract:
PROBLEM TO BE SOLVED: To evaluate performance by measuring correlation time of surfactant molecules by a nuclear magnetic resonance(NMR) analysis, thereby measuring an interaction of the molecules having correlation with performance such as foaming power, cleaning power or the like of the surfactant. SOLUTION: Correlation time of surfactant molecules is measured by an NMR analysis, a molecular motion of the surfactant is analyzed from the measured value, and performance of the surfactant is evaluated. That is, a pulse-like electromagnetic wave is emitted to surfactant water solution. And, magnitude of an interaction of the molecules is measured from time dependence or frequency dependence of the wave absorbed or reflected in the solution. For example, the wave is emitted to the solution of an equilibrated state to apply disturbance thereto, and a deviation from the equilibrated state is brought about. And, alleviating time and nuclear Overhauser effect of the molecules when the system is returned to the equilibrated state by the internal motion of the system are measured, thereby obtaining the state of the interaction of the molecules.

PURPOSE:To provide a polymerizable straight chain silicone oligomer having respectively controlled molecular weight and molecular weight distribution, excellent in hydrolysis resistance and useful for production of a graft copolymer suitable for a surface modifier for various kinds of polymers. CONSTITUTION:Polymerizable straight chain silicone oligomers of formula I [R is 1-4C alkyl or formula II (R is 1-4C alkyl); R and R are methyl, ethyl or phenyl; R and R are H or methyl; R is H or 1-4C alkyl ; (m) is 3-1000; (n) is 1-8]. The above-mentioned oligomers can be obtained by reacting a one terminal amino-modified silicone oligomer of formula III with 1.1-3 times molar (meth)acrylic acid of formula IV or its derivative at 0-100 deg.C, especially 15-40 deg.C. The compound of formula III can be obtained by reacting a compound of formula V with a (meth)allylamine-related compound of formula VI (R Is H, 1-4C alkyl or trimethylsilyl; R is H or trimethylsilyl) and then solvolyzing the resultant compound of formula VII.
Abstract:
PURPOSE:To enable the detecting of hardening behavior and condition of a reacting hardening material handily, by applying an extensional or rotary sine wave to one of two planar objects parallel facing each other. CONSTITUTION:An apparatus comprises a container with a heater 2 for holding material 5 used in producing reacting hardening material and two bar-like members 4 with planar objects 3. The two planar objects 3 are set piercing the outside and the inside of the container 1 in such a manner that the plate surfaces face each other parallel within the container. One of the two bar-like members 4 are connected to a vibrating device 6 to apply an extensional or rotary sine wave to the material for producing reacting hardening material and a sine distortion detector 8 is connected to the vibrating device 6 through an amplifier 7. The other of the two bar-like members 4 is connected to a stress detector 9 for detecting a stress transmitted through the material for producing reactive hardening material. Thus, a stress is detected with a stress detector 9 and hardening behavior and hardening condition of a reaction product can be detected from the stress and from a phase difference between both a stress wave and a distortion wave.
