Effect of Siloxane Segment Length on the Surface Composition of Polyimidesiloxane Copolymers and Its Role in Adhesion

Abstract

A series of polyimidesiloxane (SIM) copolymers, based on alpha, omega-aminopropylpoly-(dimethylsiloxane) (PDNs), 2,2-bis(4- 4-ANINOPHENOXYL phenyl)propane (BAPP) and 4,4 -oxydiphthalic- anhydride (ODPA) was synthesized in our laboratories. We investigated the effect of siloxane segment length on the surface composition of the SIM Copolymers and its role in adhesion. The aim is to elucidate the correlation between polymer structure, surface composition, and adhesion strength. Using a deconvolution computer program, composition-depth profiles of the near surface region to approximately 100 A depth were simulated from the results of angle-dependent Electron Spectroscopy for Chemical Analysis (ESCA) experiments.
