Beschreibung
Zusammenfassung:	Provided herein are butyl rubber based pressure sensitive adhesive compositions comprising low molecular weight polyisobutylene oligomers and a multifunctional crosslinker. These adhesive compositions can exhibit high adhesion and shear resistance without requiring curing at high temperature to provide the compositions with these advantageous performance properties. Also provided are adhesive tapes and methods using the disclosed adhesive compositions. En el presente documento se proporcionan composiciones adhesivas sensibles a la presión a base de caucho butílico que comprenden oligómeros de poliisobutileno de bajo peso molecular y un reticulante multifuncional. Estas composiciones adhesivas pueden presentar una alta adherencia y resistencia al cizallamiento sin requerir curado a alta temperatura para proporcionar a las composiciones estas propiedades de rendimiento ventajosas. También se proporcionan cintas adhesivas y métodos que utilizan las composiciones adhesivas divulgadas.
