|1. (WO2018107971) POLYTEREPHTHALATE-CO-SEBACATE RESIN COMPOSITION|
|Applicants:||KINGFA SCI. & TECH. CO., LTD.
|Title:||POLYTEREPHTHALATE-CO-SEBACATE RESIN COMPOSITION|
Disclosed is a polyterephthalate-co-sebacate resin composition, comprising the following components: a. a polyterephthalate-co-sebacate; and b. an alkane. The alkane is selected from at least one of hexadecane, heptadecane, octadecane, nonadecane, and eicosane; and the weight content of the alkane is 5 ppm - 1000 ppm based on the total weight of the polyterephthalate-co-sebacate resin composition. In the present invention, by adding the alkane and controlling the content of the alkane in the composition within the range of 5 ppm - 1000 ppm, not only can the polyterephthalate-co-sebacate resin have a significantly improved film-blowing property, the film thickness range thereof is < 0.3 μm and the relative deviation of film thickness is < 2.0%, guaranteeing the bubble stability and the continuity of film-blowing, and also the phenomenon of disengaging an ink from a film material during a printing process does not occur in the film material, and the phenomenon of adhesion of excessive ink to the film material also does not occur, so that the thin film exhibits a good printing performance.
