Isopropyl triisostearoyl titanate

Various investigations have considered the effects of titanate treatments on melt rheology of filled thermoplastics [17,41]. Figure 10, for example, shows that with polypropylene filled with 50% by weight of calcium carbonate, the inclusion of isopropyl triisostearoyl titanate dispersion aid decreases melt viscosity but increases first normal stress difference. This suggests that the shear flow of the polymer is promoted by the presence of titanate treatment, and is consistent with the view that these additives provide ineffective coupling between filler particles and polymer matrix [42]. 

Calvert and co-workers [49] have demonstrated the presence of isopropyl isostearate and isopropyl laurate in commercial isopropyl triisostearoyl titanate and conclude that this is the reason why the commercial product does not function as an adhesion promoter treatment at 70°C in vacuo removes these fatty acid esters. It has been suggested to the author that failures to obtain improvements in adhesion using titanates can be remedied by isolating the pure compound (B. Nordenheim, private communication, 1988). It is possible that improvements in adhesion are more likely when commercial titanates are used as additives rather than as pretreatment primers.
