- Hyperbranched Aliphatic Polyester, 2,2-dihydroxymethyl Butyric Acid, Photosensitive Polyester, Degree of Branching.
- A new kind of photosensitive polyester based on the hyperbranched aliphatic polyesters has been investigated. The hyperbranched aliphatic polyesters (polymer A) with 0.69 of the degrees of branching (DB) was prepared from 2,2-dihydroxymethyl butyric acid. Followed by end-modified with maleic anhydride (MA), end-modified hyperbranched aliphatic polyesters (polymer B) with unsaturated end groups was successfully synthesized. The polymer properties were characterized by FI-IR, 13C-NMR, GPC, TGA, respectively. The photosen-sitive hyperbranched aliphatic polyester (polymer C) based on polymer B, 4 wt% Ltd.2-Hydroxy-2-methyl-1-phenyl-1-prop-anone (Darocur 1173) as a photoinitiator, and 2-Propenoicacid-1,1'-[(1-methyl-1,2-ethanediyl) bis[oxy(methyl-2,1- ethanediyl)]] ester TPGDA(15wt% relative to polymer B) as a reactive diluent was exposed for about 1 s (2.2 KW), and formed UV-cured polymer film and regarded as a promising photosensitive material.
