The present invention discloses an encapsulation composition, an encapsulation film including the encapsulation composition, and an electronic device module. The encapsulation composition includes a polymer matrix, a tackifier and a free radical initiator. Based on 100 parts by weight of the polymer matrix, the polymer matrix includes 5 to 100 parts by weight of highly branched polyethylene (P1), 0 to 95 parts by weight of an ethylene--olefin copolymer, and 0 to 70 parts by weight of an ethylene-polar monomer copolymer. The highly branched polyethylene (P1) is an ethylene homopolymer having a branch structure and has a degree of branching of not less than 40 branches/1,000 carbon atoms. A density of the ethylene--olefin copolymer is not higher than 0.91 g/cm.sup.3. The encapsulation composition provided by the present invention has good volume resistivity, aging resistance, processability and low cost.

A method of making an adhesive for an ice protection assembly includes mixing ferrous nanoparticles into the adhesive. Removal of the adhesive for ice protection assembly inspection or repair includes heating the ferrous nanoparticles in the adhesive to soften the adhesive and allow for easy removal or repositioning of the ice protection assembly.

The invention provides hydrophilic hot melt adhesive composition with improved water wetting properties. The hydrophilic hot melt adhesive is particularly suitable in the manufacture of disposable nonwoven articles.

The present invention relates to a hydrogenated petroleum resin, and to a manufacturing method and use thereof. More specifically, it relates to a hydrogenated petroleum resin manufactured by subjecting dicyclopentadiene and an olefinic monomer to thermal polymerization and then carrying out a hydrogenation reaction, and to a manufacturing method and use therefor. 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.

The present invention discloses a method and process to laminate packaging substrates using an adhesive tape. The tape has a first heat activated adhesive which is activatable at a first temperature and a second heat activated adhesive which is activatable at a second temperature and both of which are alternatively coated on at least one surface of the tape. The method consists of laminating this aforementioned tape to a packaging substrate by following the process of: placing this tape in or on a laminating machine over the packaging substrate, heating the tape while making contact with the packaging substrate, cooling the packaging laminate until the first heat activated adhesive is set and cutting a predetermined portion of the packaging laminate before a second adhesive occurs between the tape and the packaging laminate.

Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.
