An adhesive composition comprises: (i) at least one ethylene/α-olefin interpolymer, (ii) at least one tackifÊer; and (iii) optionally at least one additive, such as a plasticizer, wax and antioxidant. Preferably, the ethylene/α-olefin interpolymer has a Mw/Mn from about 1.7 to about 3.5, at least one melting point, Tm, in degrees Celsius, and a density, d, in grams/cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship: Tm≧858.91−1825.3(d)+1112.8(d)2. The composition has relatively higher SAFT temperature and can be used in hot melt adhesives pressure-sensitive adhesives, and thermoplastic marking paints.
一种粘合剂组合物包括:(i)至少一种
乙烯/α-烯烃互聚物,(ii)至少一种粘合剂;以及(iii)可选的至少一种添加剂,例如
增塑剂、蜡和
抗氧化剂。优选地,
乙烯/α-烯烃互聚物具有Mw/Mn从约1.7到约3.5,至少一个熔点Tm(以摄氏度为单位),以及密度d(以克/立方厘米为单位),其中Tm和d的数值对应于关系式:Tm≧858.91−1825.3(d)+1112.8(d)2。该组合物具有相对较高的
SAFT温度,可用于热熔粘合剂、压敏粘合剂和热塑性标记油漆。
