ADHESIVE COMPOSITIONS AND METHOD FOR BONDING TO RUBBER

摘要

An adhesive composition which comprises(A)a conjugated diene polymer having a weight−average molecular weight of 500 to 100,000 and(B)a basic compound capable of donating an electron pair;and an adhesive composition which comprises(A)a conjugated diene polymer having a weight−average molecular weight of 500 to 100,000,(C)a compound having in the molecule at least three functional groups selected from among acryloyloxy,methacryloyloxy,and functional groups represented by the general formula(I),and(D)a compound having one or two acryloyloxy or methacryloyloxy groups in the molecule:(I)(wherein R1,R2 and m are each as defined in the description).Strong adhesion between an adherend and rubber can be attained by coating at least part of an adherend surface with the above adhesive composition to form an adhesive layer,irradiating the adhesive layer with ultraviolet light or a radiation at need,bringing a green rubber into contact with the adhesive layer,and then vulcanizing the green rubber while pressing the green rubber to the adhesive layer.The rubber−adherend composites thus obtained are useful for rubber reinforcements and rubber articles.
