“…On the other hand, the peel strength decrease after a certain immersion time or solution temperature can be attributed to the dehydrochlorination process which occurs at longer treatment times and higher temperatures [10,11]. Furthermore, as the treatment time or solution temperature increases, the percentage of polar groups in the interphase layer will increase.…”

Polymer adhesion and its evaluation are very important both from academic and industrial points of view. Adhesion phenomenon depends mainly on the strength of interfacial bonds and the deformability of adhering partners, which act as another energy absorbing term. Using a combination of acid-base interactions and a coupling agent at the interface of styrene-butadiene (SBR) -polyurethane system, a synergistic adhesion promotion was observed. The SBR surface was treated with an acidi ed aqueous solution of calcium hypochlorite to obtain polar groups, which can interact with the isocyanate groups of the polyurethane system. Aminopropyltriethoxysilane, a coupling agent, was also deposited at the SBR surface, after treating it with the aforementioned solution. The polar groups on the SBR apparently interact with the OH sites of the coupling agent at the surface and push the amino groups toward the polyurethane surface. This interesting nding, synergistic adhesion promotion, was attributed to the tortuous path for the crack growth at the interface, which was created by formation of the interfacial bonds with different strengths (heterogeneous bond strength). Furthermore, to obtain the highest synergistic effect, it seems that certain ratio of bonds with different strengths should be formed. The ratio itself depends on the deformability ratio of the adhering materials.

Summary: The present work is focused on the characterization of the surface properties and the mechanical properties of chlorinated polyisoprene films. Cross‐linked polyisoprene films were treated with acidified hypochlorite solution and the influence of the chlorination time on the surface properties was determined by spectroscopic techniques including FT‐IR spectroscopy and X‐ray photoelectron spectroscopy (XPS). The surface morphology was investigated by scanning electron microscopy (SEM), optical microscopy and contact angle measurements. In addition, the effect of the chlorination time on the tensile strength and ageing stability of natural rubber latex gloves was investigated.

ABSTRACT:Photografting reaction onto styrene-butadiene rubber (SBR) as a function of monomer concentration, grafting method, irradiation time, and the carbon black content has been studied using ultraviolet (UV). Glycidyl methacrylate and benzophenone are used as monomer and initiator, respectively. The occurrence of graft reaction onto SBR surface is identified by infrared attenuated total reflection (IR-ATR) analysis. The degree of monomer graft increases with monomer concentration and tends to level off at high monomer concentration (Ͼ8.3M/L). Graft ratio also increases with UV irradiation time. Carbon black content is found as one of important factors that determine the monomer graft efficiency. The amount of monomer graft onto SBR decreases with increasing carbon black content and it is attributed to the reduction of irradiation absorbance due to the presence of carbon black. The occurrence of reaction between glycidyl methacrylate grafted SBR and nylon-6 via melt phase reaction is also identified using IR-ATR analysis.
