ABSTRACT
An attempt to replace a wet chemical chlorination (with halogenating agents in organic solutions) of the styrene-butadiene elastomer surfaces with a clean plasma technique has been undertaken. Plasma generated by an rf discharge (13.56 MHz, plate electrode reactor) in CHCl3 vapor or in a mixture of CHCl3 and oxygen was used. The elastomer surfaces were investigated by FTIR spectroscopy, contact angle measurements, and T-peel tests. It has been found that the CHCl3 plasma (without O2) generated at relatively low powers is an effective tool for the surface chlorination. This process. however, is possible only when the appropriate concentration of butadiene blocks there is in the styrene-butadiene block copolymers. For 69 wt. % of butadiene, the peel strengths of the plasma treated (with the discharge power of 10 W) is approx. 56% higher than that for the material chemically chlorinated and approx. 3 times higher in comparison with the non-treated surface.

Podjęto próbę zastąpienia mokrego chemicznego chlorowania powierzchni elastomeru styren owo-butadienowego przez chlorowanie w parach CHCl3 i tlenu, z wykorzystaniem rf (13.56 MHz) plazmy generowanej w elektrodowym reaktorze. Powierzchnie elastomerów scharakteryzowano wykonując badania absorpcji w podczerwieni (FTIR), pomiary kąta zwilżania oraz testy zrywania. Ustalono, że plazma generowana bez tlenu i przy relatywnie niskiej mocy jest efektywnym narzędziem do chlorowania powierzchni badanych elastomerów.
