DIRECTLY ATTACHING, HALOGEN-FREE, FAST-DRYING, HEAT-SEALING BINDER FOR SEALING POLYESTER FILMS TO POLYSTYRENE, POLYESTER OR PVC

The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.

FUNCTIONALIZED POLY(2,6-DIMETHYL PHENYLENE OXIDE) OLIGOMERS CONTAINING DICYCLOPENTADIENE, METHOD OF PRODUCING THE SAME AND USE THEREOF

The invention discloses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers containing dicyclopentadiene, a method of producing the same and use thereof. The cured products of the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention exhibit low dielectric constant, low dissipation, and high glass transition temperature. As the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention have number-average molecular weight ranging from 2500 to 6000 g/mol, the substrate made of theses functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers can pass the pressure cook test. Besides, the low dissipation factor characteristic the functionalized poly(2,6-dimethyl phenylene oxide oxide) oligomers of the invention can only be demonstrated at number-average molecular weight higher than 2500 g/mol.

Hydrogenated petroleum resin, and production method and use therefor
11186754 · 2021-11-30 ·

A hydrogenated petroleum resin, and a manufacturing method and use thereof, are provided. More specifically, a hydrogenated petroleum resin manufactured by subjecting dicyclopentadiene and an olefinic monomer to thermal polymerization and then carrying out a hydrogenation reaction, and a manufacturing method and use therefor are provided. The hydrogenated petroleum resin has the advantage of being useful in practical applications, since the petroleum resin is manufactured via thermal polymerization using inexpensive raw materials and on the contrary to conventional catalytic polymerization, a catalyst elimination process can be excluded. The hydrogenated petroleum resin produced in this way can be applied to, for example, an adhesive agent used in environmentally friendly sanitary goods, because the petroleum resin has excellent compatibility, adhesiveness and heat resistance, and has no bad odor.
