ABSTRACT:
A halogenated polyether is provided having a chemical structure which has been found to possess the requisite characteristics for satisfactory service as a promoter of good adhesion between a polymeric surface (e.g., a polyethylene terephthalate tire cord) and an elastomeric material (e.g., rubber). The halogenated polyether may be formed by (1) the reaction of an organic polyhydroxy compound with epihalohydrin (e.g., epichlorohydrin) to create ether linkages, (2) the epoxidation of the ends of the ether chains which extend from the residual portion of the organic polyhydroxy compound, and (3) the substantial hydrolysis of the epoxy groups (as described). The resulting halogenated polyether is substantially free of epoxy groups, contains at least one 2-halomethyloxyethylene unit, and contains 2,3-dihydroxypropyl end groups (as described). Such halogenated polyether optionally may be provided in the form of an oligomer (as described). The novel compounds when handled are not believed to require the cumbersome worker protection measures which are commonly being utilized when epoxy compounds are employed in similar end uses.
