ALKYLPHENOL FORMALDEHYDE RESIN AND RUBBER COMPOSITION CONTAINING THE SAVE

Title:

ALKYLPHENOL FORMALDEHYDE RESIN AND RUBBER COMPOSITION CONTAINING THE SAVE

Document Type and Number:

Japanese Patent JPH02284910

Kind Code:

A

Abstract:

PURPOSE:To obtain the title resin which has a specific <1>H-NMR peak intensity and gives an olefinic rubber high heat resistance, when added thereto. CONSTITUTION:The subject resin has 0.1 to 7.0 absorption intensity at 3.7 to 4.2delta(ppm), when the absorption intensity of hydrogen at 4.3 to 5.1delta(ppm) chemical shift of H is defined as 100 in the NMR spectroscopy (<1>H-NMR). The resin is added to 100 pts.wt. of an olefinic rubber in an amount of 0.1 to 50 pts.wt. to give a rubber composition of high heat resistance. The resin is obtained by heating an alkylphenol and formaldehyde in the presence of an alkali catalyst.
