Abstract: PROBLEM TO BE SOLVED: To provide a method by which the thermal degradation of a sulfur-vulcanized rubber can be nondestructively, conveniently and accurately predicted without performing a heat aging test.
SOLUTION: In measurement of the thermal degradation of a sulfur-vulcanized natural rubber composition, signal strength is determined on a sensitivity condition of an amplitude ratio (S/N) of 1,000:1 of the maximum signal strength in unreacted rubber compounds to noise comprising a baseline, and a representative value of the quantity of coupling sulfur coupled to a rubber molecule is found by formula in direct excitation measurement of a carbon nucleus (
13 C) by a solid high resolution nuclear magnetic resonance method using a magic angle spinning method (i), a representative value Gg of a sulfur bridge coupled between two rubber molecules is found by formula (I) based on a modulus (Gf) when the vulcanized rubber is extended to 100% in a tension test, the composition quantity (a volume fraction ϕ)of carbon black and the adsorption quantity of DBP (dibutyl phthalate) of the carbon black (ii), and the thermal degradation of the sulfur-vulcanized natural rubber composition is predicted based on a coupled S/Gg value (iii).

Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire that discharges air bubble formed in an adhesive sealant layer as much as possible and exhibits high sealing effect, and its manufacturing method.
SOLUTION: In the pneumatic tire, an adhesive sealant layer 8 formed by decomposing rubber component by peroxide is arranged inside an inner liner layer 7 in a tread section 1, and is covered with a cover rubber layer 9. A twisted thread 10 for releasing gas generated in the adhesive sealant layer 8 is arranged between the inner liner layer 7 and the cover rubber layer 9 so that at least one end extends from an edge 9a of the cover rubber layer 9. Both ends in the tire circumferential direction of a sheet material 13 of rubber composite which denatures to the adhesive sealant layer 8 are cut with inclined planes 13a inclining with respect to the thickness direction, the sheet material 13 is annularly bonded together via the inclined planes 13a to form the adhesive sealant layer 8.
