概要 The synthesis and photopolymn. of alk.-developable hyperbranched polyurethane (HBPUMA-COOH) were examd. The reaction of dicyclohexylmethane 4,4'-diisocyanate (CMDI) and trimethylolpropane (TMP) in the presence of 2-methacryloyloxyethyl isocyanate (MOI) was carried out to give the sol. hyperbranched polyurethane (HBPUMA) with terminal methacryloyl groups in satisfactory yield. After that, HBPUMA-COOH was synthesized by the reaction of HBPUMA and cis-1,2,3,6-tetrahydrophthalic anhydride (THPA). The photoradical polymn. of HBPUMA-COOH was examd. in the presence of 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropan-2-one (Irgacure 907) as a photoinitiator in the film state upon UV irradn. to afford the corresponding cured film quant. It was found that the tensile strength of the resulting cured film of HBPUMA-COOH was higher than those of the HBPUMA and linear one. The neg. patterning property of HBPUMA-COOH also had 5 micro m line and space pattern resoln. by UV irradn. with 150 mJ/cm2. Furthermore, it was cleared that the photocured HBPUMA and HBPUMA-COOH showed very low birefringence.
