| 摘要 |
The present invention provides a thermoplastic resin composition that gives a solar cell sealing sheet having, even without being crosslinked, good mechanical strength, solar cell sealability, transparency, and weatherability. The thermoplastic resin composition of the present invention comprises 1 to 95 % by weight of a propylene-based polymer (A) and 5 to 99 % by weight of a copolymer (B) with at least one ±-olefin having 2 to 20 carbon atoms other than propylene, wherein (A) satisfies the following (i) and (ii), and (B) has a melting point below 80°C or does not show a melting point as measured by a differential scanning calorimeter (DSC).
(i) Melting point measured by a differential scanning calorimeter (DSC) method is in the range of 80 to 135°C.
(ii) Endotherm attributable to crystal melting is not observed at 140°C or more in the endothermic curve measured by a differential scanning calorimeter (DSC) method. |
