Poly(dimethylsiloxane) has been used in many fields and a variety of functional groups has been incorporated into poly(dimethylsiloxane), derivatives of this well-known silicone rubber which have specific applications based on those incorporated functional groups. In this project, synthesis and characterization of cinnamated poly(dimethylsiloxane) were investigated. The intermediates of synthesizing cinnamated poly(dimethylsiloxane) were characterized by H and C NMR. Based on polymerization of cinnamated cyclotetrasiloxane catalyzed by CF3SOOOH, the cinnamate moieties were incorporated into poly(dimethylsiloxane) and cinnamated poly(dimethylsiloxane) was characterized by H and C NMR and GPC. Taking advantage of spectral changes of Uvvis and FT-IR, the properties of crosslinking of synthesized cinnamated poly(dimethylsiloxane) were investigated. The synthesized cinnamated poly(dimethylsiloxane) was used to fabricate patterns with micro-scale features of dots, holes and lines by direct photopatterning. All patterns with size of features from 125 urn to 15 urn were demonstrated by light microscopic observations.
