  1. Introduction

  Recent Takacs' review paper [25] provides very detailed information relating to the history of mechanochemistry starting with prehistoric times, when reactions were initiated during grinding and rubbing accidentally. It also includes the main developments until the presently achieved results.

  The mixture was subjected to grinding using a planetary ball mill under different conditions, to investigate their MC reactions. The grinding causes dehydrochlorinating reaction, forming CaOHCl and [CH=CH]x. The reactivity against PVC of CaO is superior to that of Ca(OH)2, but all the same, the reaction yield is advanced as the grinding progresses.
