The present invention provides a chlorinated polyvinyl chloride resin that provides a molded article having excellent heat cycle characteristics and excellent weather resistance, as well as a resin composition for molding and a molded article each including the chlorinated polyvinyl chloride resin. Provided is a chlorinated polyvinyl chloride resin having an average of a ratio (A/B) of a peak intensity A observed in a range of 300 to 340 cmto a peak intensity B observed in a range of 1,450 to 1,550 cmof 3.5 to 40.0 in Raman imaging measurement by Raman spectroscopy.

Chlorinated vinyl chloride resin

The present invention provides a polyvinyl acetal resin which leaves less fine undissolved matter when dissolved in an organic solvent and thus can improve productivity particularly when used as a binder for a ceramic green sheet, and which can also provide a ceramic green sheet having excellent toughness and enables production of a highly reliable multilayer ceramic capacitor. Provided is a polyvinyl acetal resin having: a wavenumber A (cm) of a peak within a range of 3,100 to 3,700 cmin an IR absorption spectrum measured using an infrared spectrophotometer; and a hydroxy group content (mol %), the wavenumber A of the peak and the hydroxy group content satisfying relations of the following formulas (1) and (2):[(3,470−)/Hydroxy group content]≤5.5  (1)(3,470−)≤185  (2)wherein A is a wavenumber which is lower than 3,470 cmand at which a transmittance a (%) satisfying [100−(100−X)/2] is exhibited, where X (%) is a minimum transmittance of the peak within the wavenumber range of 3,100 to 3,700 cm.

Polyvinyl acetal resin

The present invention provides a chlorinated polyvinyl chloride resin that enables excellent continuous productivity in molding and that enables a molded article to have both processability and unevenness-preventing properties. Provided is a chlorinated polyvinyl chloride resin having an average of a ratio (A/B) of a peak intensity A observed in a range of 660 to 700 cmto a peak intensity B observed in a range of 600 to 650 cmof 0.50 to 2.00 in Raman imaging measurement by Raman spectroscopy.

Chlorinated vinyl-chloride-based resin

The present invention provides a chlorinated polyvinyl chloride resin that enables the production of a molded article that maintains high adhesion strength even when used in a form subjected to high pressure and is less susceptible to defects such as cracks due to insufficient strength, as well as a resin composition for molding and a molded article each including the chlorinated polyvinyl chloride resin. Provided is a chlorinated polyvinyl chloride resin having an average of a ratio (A/B) of a peak intensity A observed in a range of 300 to 340 cmto a peak intensity B observed in a range of 1,450 to 1,550 cmof 0.1 or more and 3.5 or less in Raman imaging measurement by Raman spectroscopy.

Chlorinated vinyl chloride-based resin

The present invention provides a chlorinated polyvinyl chloride resin that enables a molded article to have both processability and unevenness-preventing properties and also high gloss. Provided is a chlorinated polyvinyl chloride resin having an average of a ratio (A/B) of a peak intensity A observed in a range of 660 to 700 cmto a peak intensity B observed in a range of 600 to 650 cmof 0.50 to 2.00 in Raman imaging measurement by Raman spectroscopy, and having a standard deviation of the ratio (A/B) of the peak intensity A to the peak intensity B of 0.100 to 0.200 in Raman measurement by Raman spectroscopy.

There is provided an interlayer film for laminated glass with which protrusion of an interlayer film portion in the TD direction can be suppressed at the time of producing laminated glass. In the interlayer film for laminated glass according to the present invention, when, in the MD direction of the interlayer film, a birefringence index of the first surface part, a birefringence index of the second surface part, and a birefringence index of the center part are defined as &#x394;nMDA, &#x394;nMDB, and &#x394;nMDC, respectively, &#x394;nMDA, &#x394;nMDB, and &#x394;nMDC each are 0.25&#xd7;10or less.

Interlayer for laminated glass and laminated glass

A novel cycloolefin copolymer that can be employed in the production of molding with fewer defects, for example, fewer gel particles (fish eyes). There is provided a cycloolefin copolymer comprising 80 to 20 mol % of repeating units derived from an &#x3b1;-olefin monomer and 20 to 80 mol % of repeating units derived from at least one cycloolefin monomer selected from the group consisting of monomer of the general formula (I), monomer of the general formula (II), monomer of the general formula (III), monomer of the general formula (IV) and monomer of the general formula (V), wherein with respect to the repeating units derived from cycloolefin monomer, the proportion thereof being present in the form of dimer (Rd) is 50 mol % or below and the proportion thereof being present in the form of trimer (Rt) 5 mol % or above.

Cycloolefin copolymer

A multi-layer sheet of the present invention comprises a thermoplastic resin foam sheet, a reinforcing sheet layered on integrated with at least one side of the thermoplastic resin foam sheet; the reinforcing sheet being formed by a non-woven fabric which comprises non-meltable fibers which are interwound with one another and which are bound together with a thermoplastic resin, the thermoplastic resin foam sheet having an aspect ratio Dz/Dxy of bubbles of 1.2 or more, and an expansion ratio of 5&#x2dc;50 cc/g, and therefore the sheet is excellent in bending strength, compressive strength, thermo-forming property and dimensional stability as well as lightweight property, and so can ideally be used for an upholstery material for vehicles, a heat-insulation material, a buffer material and the like.
