Getter for packaging, highly active calcium oxide, and method for preparing highly active calcium oxide

The invention, more particularly, to a first organopolysiloxane compound, and represented by the formula (1) relates to a production method of an active calcium, and the highly active calcium oxide and included in the packaging getter, said getter for formula (2) second production of active calcium, and the highly active calcium oxide and included in the packaging getter, said getter comprising the active material for the binder and adsorbent for the getter is prepared from a composition for a binder containing an organic polysiloxane compound represented by the It relates to a method. Formula 1 [Formula 2] Wherein R Among examples of the R The amino group, silyl group, germyl group, and the R Wherein n is an integer of 10 to 10,000, Wherein a is an integer from 0 to 9,999, Wherein b is an integer from 1 to 10,000, 1 is ≤ a + b ≤ 10,000. Packaging getter of the present invention exhibit excellent film properties, including the superior gas permeability and durability, the binder, and the most suitable for the active calcium oxide getter shows the adsorption properties superior moisture or oxygen. Initial absorption rate, high specific surface area, calcium oxide, a getter, a binder, a silicone resin, water, suction, the thin film, an organic EL device
