Abstract: To provide a sheetlike article for laundry which is freed from the scattering or leak of the contents, facilitates arbitrary dispensing and exhibits excellent detergency even when used alone, sheetlike water-soluble substrates are arranged on both surfaces of a thin layer made of a doughy non-phosphate detergent composition which contains nonionic surfactant(s), alkaline agent(s) and sequestering agent(s) and has a penetration hardness at 25° C. of from 0.1 to 10 kg/cm2.

Abstract: A dimension measuring apparatus for measuring the dimensions of a secondary electron emission object has a scanning electron microscope main body with a display, and a dimension measuring section connected to the main body. The dimension measuring section has a cursor setter for displaying cursors on the display. A memory stores image signals which are divided into picture elements and assigned to addresses. The image signals are used as image data. A CPU section receives the image data from the memory, obtains reference points for designating two ends of a line corresponding to a dimension of a sample to be measured based on the received image signals, and measures the dimension of the sample.

Abstract: m-Isopropenylphenol oligomer which is useful for the production of synthetic resins such as epoxy resins is produced by polyermizing m-isopropenylphenol at a temperature of 135.degree. to 230.degree. C. using a catalytic amount of an acid catalyst in the presence or absence of a solvent, or freezing m-isopropenylphenol in the presence or absence of an acid catalyst.

Abstract: An oligomer of m-isopropenylphenol is produced by subjecting m-isopropenylphenol to thermal polymerization in the absence of a catalyst.

Abstract: A method is disclosed for adhering rubber and reinforcing materials simultaneously with vulcanization, without defects such as fume and bloom phenomena of formaldehyde-acceptors, deliquescence and blocking, which is characterized in the use of a vulcanizable rubber composition containing an improved co-polycondensate resin which is prepared by condensing (A) a resol type pre-polycondensate prepared by at least one phenol and formaldehyde or acetaldehyde in the presence of an alkaline catalyst, and (B) resorcinol, m-aminophenol or the like, while distilling off water present in the reaction system, and then solidifying the reaction mixture.

Abstract: An epoxy resin of the formulae (I) and/or (II), ##STR1## wherein R and R' are each hydrogen atom or an alkyl group having 1 to 3 carbon atoms and n is a mean value satisfying the equation, 0<n.ltoreq.2, which is excellent in heat resistance, flexibility, curability and the like, and is useful in paints, adhesives, civil engineering and construction industry, electric appliances and the like.
