PROCESS TO MODIFY NON GLYCIDYL FUNCTIONAL IMPURITIES OF GLYCIDYL ESTERS TO BE USED IN FURTHER RADICAL POLYMERISATION
摘要
<p>The present invention relates to a process to modify the non glycidyl functional products occurring in industrially produced glycidyl esters, which are currently used in the synthesis of radical polymerisable acrylic or methacrylic acid derivatives, to be further reacted too resins for coating applications. The process to modify non glycidyl functional impurities in glycidyl esters of branched alkane carboxylic acids, by reacting the fraction of non-glycidyl functional products with ethylenically unsaturated anhydride. Another aspect of the present invention is formed by the cured coating films derived from the hereinbefore defined coating compositions and applied an a shaped substrate, and more in particular an automotives.</p>
