Silicone grafted

In relation to consumer uses of possible concern for this CICAD, data from the Women s Environmental Network indicate that butyltin stabilizers have been detected in the non-woven polypropylene topsheet of babies nappies (diapers). It is possible that this could relate to the last of the three key uses described above, in that the topsheet could be of silicone-grafted polypropylene (or, as discussed below, the butyltin may be present because of its use as a catalyst in the production of an antioxidant in polyolefin films).

Many silicones grafted with organic entities are commercially available and others can be synthesized [50] giving rise to numerous organic crosslinking methods, only those involved in IPNs will be discussed in this review.

Measurements have been made, in the AFM contact mode, of both chemical and mechanical local attractive or adhesive forces of model substrates. Assuming that the main technical uncertainties have been listed and minimized, surface force measurements were first performed on chemically modified silicon substrates (grafted with hydroxyl, amine, methyl, and ester functional groups). The surface chemistry contribution (in particular, its hydrophilic features) is dominant in the measurement of the adhesion force. A linear relationship has been obtained between the van der Waals component of the thermodynamic work of adhesion and the surface energy of the silicon grafted substrates.
