Abstract
An aqueous emulsion comprising an aqueous continuous phase and a discontinuous oil phase comprising particles having an interpenetrating network (IPN) comprising: i) an MQ resin, ii) a polyorganosiloxane and iii) an organic polymer.
Claims11
An aqueous emulsion comprising an aqueous continuous phase and a discontinuous oil phase comprising particles having an interpenetrating network (IPN) comprising:
- i) at least 10 wt % MQ resin substantially free of radically polymerizable functional groups;
- ii) at least 25 wt % polyorganosiloxane;
- and
- iii) from 1 to 50 wt % organic polymer having a glass transition temperature of from 0 to 150° C.

A method of making an aqueous emulsion comprising an aqueous continuous phase and a discontinuous oil phase including the steps of:
- (1) obtaining or preparing an aqueous emulsion comprising a discontinuous oil phase comprising particles which comprise:
- i) MQ resin substantially free of radically polymerizable functional groups;
- ii) polyorganosiloxane;
- and iii) ethylenically unsaturated organic monomers selected from one or more of:
- acrylates, vinyl esters, vinyl aromatics, olefins, 1,3-dienes, and vinyl halides;
- (2) polymerizing the ethylenically unsaturated organic monomers to form an interpenetrating network within the particles.
