Hybrid-type polyester resin, resin composition for formation of film, and polyester film and textile
Patent number: 9873978Abstract: Provided is a hybrid-type polyester resin which, when used in processing a base material such as textile or PET film, can impart excellent flame retardance to the base material. The hybrid-type polyester resin can be inhibited from scattering high-temperature drips, even if the hybrid-type polyester resin burns. The hybrid-type polyester resin comprises both a polyester resin and a siloxane prepared from silica and an alkoxysilane. Therefore, the hybrid-type polyester resin retains the excellent properties inherent in polyester resin and exhibits extremely excellent flame retardance by virtue of hybridization with the siloxane. Even if the hybrid-type polyester resin burns, the hybrid-type polyester resin is less susceptible to deformation, and is therefore inhibited from scattering high-temperature drips.Type: GrantFiled: October 28, 2010Date of Patent: January 23, 2018Assignee: GOO CHEMICAL CO., LTD.Inventors: Koji Maeda, Yusuke Numamoto -
