ABSTRACT:
A novel ionomeric silane coupling agent is disclosed and its use in bonding a matrix polymer to a mineral substrate is described. The coupling agent is prepared by partially neutralizing the combined acid functionality present in a mixture of an acid-functional silane (or metal salt thereof) and an acid-functional film former with a metal ion. The coupling agent greatly improves bond strength in moist environments and is particularly suitable for use in formulating filled injection molding compositions.
