Versuchsvorschrift
70 grams of mercaptopropyltrimethoxy silane and 35.5 gms. of allylurea were weighed into a flask equipped as in Example 1. The contents of the flask were heated to about 90° C. and 0.3 gm. of Vazo 64 was used. The temperature indicated an exotherm to about 145° C. which was controlled back down to about 100° C. for a total of 6® hours and it was then cooled. Titration of a sample showed about 71% reaction of the mercaptan. The material was filtered. The proton NMR analysis showed a structure consistent with the title compound. There was unreacted allylurea present at less than 25%.
