How can allyl methacrylate be solvent-free modified? And can modified allyl methacrylate in-situ modify styrene-acrylic emulsion?

In a new  study, a solvent-free method to modify allyl methacrylate (AMA) with 1,1,1,3,5,5,5-heptamethyltrisiloxane (MDHM) through hydrosilylation reaction catalyzed by Speier’s catalyst is provided. The results from Fourier transform infrared spectroscopy (FT-IR) and ultraviolet spectrometer (UV) clearly indicated that AMA was modified by MDHM through the hydrosilylation on the CC of isopropenyl segment with the CC of propenyl group remaining to obtain unsaturated acrylate containing organosiloxane chain segment.

Organosiloxane chain segments successfully introduced

The application of MDHM modified AMA in waterborne self-matting styrene-acrylic emulsions was also studied through in-situ copolymerization. The surface gloss, wettability, chemical composition and morphology of the prepared emulsion coating films were investigated. The results showed that organosiloxane chain segments were successfully introduced, which made film get a fine rough surface, which increase the film surface water contact angle and help to obtain a kind of waterborne semi-gloss styrene-acrylic resin film
