Title:
RESORCINOL-FORMALDEHYDE-p-ALKYLPHENOL COCONDENSATE AND RUBBER COMPOSITION CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2007009047
Kind Code:
A
Abstract:
To obtain a cocondensate that provides excellent adhesion performance when used for vulcanization adhesion between rubber and a reinforcing material, has excellent hardness and crash-resistant characteristics and reduced rolling resistance and a rubber composition containing the same.
The cocondensate is a condensate obtained by reacting a p-alkylphenol represented by general formula (1) (R is a 1-3C alkyl group) with formaldehyde in the presence of an alkali catalyst to give a resol type condensate and further reacting the resol type condensate with resorcinol in the presence of an acid while distilling away water.
