Beschreibung
Zusammenfassung:	The present invention provides a rubber-based pressure-sensitive adhesive composition which contains a rubber-based base polymer, the rubber-based base polymer comprising an isobutylene-based polymerhaving a polydispersity coefficient, (weight-average molecular weight)/(number-average molecular weight), of 4 or less. A 50 mum-thick rubber-based pressure-sensitive adhesive layer formed from the rubber-based pressure-sensitive adhesive composition has a moisture permeability at 40 DEG C and 92% RH of 50 g/(m2*day) or less. The rubber-based pressure-sensitive adhesive composition of the presentinvention can form a rubber-based pressure-sensitive adhesive layer which has low moisture permeability and has so high durability that the adhesive layer can be inhibited from suffering troubles including lifting and peeling even in high-temperature environments. 本发明为包含橡胶类基础聚合物的橡胶类粘合剂组合物，所述橡胶类基础聚合物包含多分散度(重均分子量/数均分子量)为4以下的异丁烯类聚合物，由所述橡胶类粘合剂组合物形成的厚度50μm的橡胶类粘合剂层的在40℃、92％R.H.下的透湿度为50g/(m·天)以下。利用本发明的橡胶类粘合剂组合物，能够形成透湿性低且在高温环境下也能够
