실험 절차

Acryloxypropenyldimethylchlorosilane was prepared by a modification of Example 2 of U.S. Patent 3,746,734, to Berger et. al., using propargyl acrylate and dimethylchlorosilane as reactants. This product was then reacted with diethylamine. The resulting N,N-diethylaminoacryloxypropenyldimethylchlorosilane was then condensed with the 12000 MW and 28000 MW silanol terminated silicones utilized in Examples 1-16. The resulting acrylate terminated silicones were designated D and E, respectively.
