AbstractPolymeric Curing agent modified with hexamethyldisilazane (PCA-D), or with hexamethylcyclotrisilazane (PCA-T), was used to improve the mechanical properties of hydroxyl-teminated polydimethylsiloxane (PDMS) rubber. The structure and the gel time of PCA were characterized by (29)Si NMR and shear viscosity measurement, respectively. The PCA modified with silazanes was more stable in storage than that without treatment (PCA-0). Chemical bonds were formed during the reaction of silazanes and PCA according to (29)Si NMR results. The crosslink density (gamma(e)) and the mechanical properties of PCA/PDMS rubber were determined by swelling equilibrium and stress-strain tests. It was found that PCA treated with both silazanes could better enhance the mechanical properties of PCA/PDMS rubber compared with PCA-0. PCA-T/PDMS rubber, with additional crosslinks, was the best among the three types of PCA/PDMS rubber on the mechanical properties. (C) 2008 Wiley Periodicals, Inc.
