Further, 50 wt % of the film former matrix is a crystallizable polymer which: (i) exhibits a crystallization enthalpy of <1 J/g in a DSC measurement on cooling at 10K/min from at least 30K above a peak temperature of the melting peak of the polymer or 100 C., whichever is greater; and (ii) exhibits a crystallite fusion enthalpy of 15 mJ/mg in its pure state in a first heating curve of a DSC measurement at 10K/min and after storage for one month from 15 to 25 C. and relative humidity from 30 to 70%.

Provided are a film and an electric device comprising the same. The film comprises at least one modified polyolefin resin layer. A resin forming the modified polyolefin resin layer comprises 1-100% of modified polyolefin resin. A main chain in the modified polyolefin resin is an ethylene--olefin copolymer. A grafted branched chain in the modified polyolefin resin is selected from a compound formed by a vinyl monomer comprising one or more of anhydride group, hydroxyl, ester group, carbonyl, acylamino, pyridyl, epoxy, pyrrolidonyl and glycidyl. A molecular weight of the grafted branched chain is 150-8000 g/mol. The film prepared from the modified POE layer with the main chain and the grafted branched chain has excellent anti-PID performance. The layers have a better adhesive property without a laminated interface therebetween. The co-extruded film further has an excellent water vapor barrier property, a relatively high insulating property and a relatively high light transmittance.

Provided is an elastic infill for artificial turf. The elastic infill is produced by pelletization of an elastomer composition comprising a silane coupling agent and a mixture of an olefin copolymer-containing base resin and an inorganic filler. The silane coupling agent is present in admixture with the mixture. Alternatively, the silane coupling agent may be grafted onto the olefin copolymer to allow cross-linking of the olefin copolymer in the presence of water.
