ABSTRACT:
This invention involved the discovery of novel polymers used as adhesives and a process for their preparation. The polymers were prepared by the nucleophilic substitution, at room temperature, of PVC with substituted alkyltrialkoxysilanes, which can be cured at room temperature to give adhesion of PVC to hydrophilic substrates. These polymers are particularly useful as adhesion promoters in ion-selective electrodes. The invention also involved the application of these adhesive primers to planar electrode substrates to give greatly improved performance in the response of ion-selective electrodes.
