Other Methods of Effecting Mechanicochemical Reactions

This type of approach has also been used to attach antioxidants to unsaturated polymers. The novel approach of Scott in the 1970s (Scott, 1984) using the technique employed by Watson enabled the attack of substituted allyl mercap-tans and disulfides to olefinic double bonds employing the Kharasch reactions. 

Mechanicochemical reactions can occur during processing, when the polymer is converted to a finished product. The chain scission can occur in both saturated and unsaturated polymer backbones. For example, during processing in a screw extruder, backbone scission in polypropylene produces long-tail
