Figure 5.8 Infrared spectra of calcium carbonate whiskers after modification with stearic acid at different concentrations.

There are many studies on calcium carbonate whisker surface modification. Some scholars, for example, Li et al., believe that the calcium carbonate whisker surface can form chemical bonds with the molecules of stearic acid. Infrared spectra are shown in Figure 5.12. [Pg.224]

Semicompatible plasticizing polymers such as chlorinated polyethylene (CPE), ethylene-vinyl acetate (EVA), vinylchloride graft polymers and inorganics such as stearic acid-coated calcium carbonate are also used for impact modification of PVC. [Pg.53]
