    摘要: Propylene-based polymers (A) are provided which, when used as pressure-sensitive adhesives to various adherends, show a desired initial adhesion and will not contaminate the adherends and which have excellent pellet handling properties. Pellets of the invention contain the propylene-based polymers (A). Pressure-sensitive adhesives of the invention contain the propylene-based polymers (A). The propylene-based polymer (A) includes 65 to 80 mol % of a structural unit derived from propylene, 5 to 10 mol % of a structural unit derived from ethylene and 15 to 25 mol % of a structural unit derived from a C4-20 α-olefin (wherein these percentages are calculated based on 100 mol % of the total of the structural unit derived from propylene, the structural unit derived from ethylene and the structural unit derived from a C4-20 α-olefin) and has a heat of crystal fusion of 5 to 45 (J/g) as measured by DSC. Compositions of the invention contain the propylene-based polymers (A).
