Abstract
The present invention provides an adhesion enhancer and a polymer composition containing the adhesion enhancer for enhancing the adhesion performance of polymer composition substrates to a primer. The adhesion enhancer of the present invention includes an alcohol, a phenol or another organic compound having a hydroxyl group of the alcohol or phenol and another functional group as supported by a porous material, or a master batch prepared by mixing a polymer with the above organic compound as supported on a porous material. The polymer composition substrate obtained by adding more than 0.5 part by weight of the adhesion enhancer based on 100 parts by weight of the polymer to a normal polymer composition shows good adhesion to a primer having an isocyanate group without a separate process of making a coarse surface of the substrate or an abrasion process using an organic solvent.
