The present invention provides a process for producing an encapsulating material for solar cell which makes high-speed crosslinking possible and causes no blister phenomenon without significant restrictions being imposed on the conditions for molding the encapsulating material. The present invention provides a process for producing the encapsulating material for solar cell including impregnating a molded form of an ethylene copolymer with an organic peroxide in a liquid state at normal temperature which shows a decomposition temperature (a temperature at which the half-life period is one hour) of not higher than 150&#xb0; C. A process for producing the encapsulating material for solar cell in which dialkyl peroxide (A) and an organic peroxide (B) selected from peroxycarbonate and peroxyketal at a ratio by weight of 10/90 to 90/10 of (A) and (B) in a liquid state impregnate the molded form of the ethylene copolymer is a preferable embodiment of the present invention.

Propylene resin composition and use thereof

Proposed herein is an ionomer composition which comprises a reaction product of from 90 to 99.5% by weight of an ethylene copolymer-type ionomer (A) with from 0.5 to 10% by weight of an olefin copolymer (B) having epoxy groups in its side chains, and from 5 to 200 parts by weight, based on 100 parts by weight of said reaction product, of an olefin-type thermoplastic elastomer (C). The proposed ionomer composition is excellent in scratch resistance and flexibility and exhibits a reduced 'luster reappearance'.
