    • A method of preparing a hot melt adhesive composition, comprising (A) feeding a polymer blend into an extruder; wherein the polymer blend comprises (a) a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4-C10 alpha-olefin; and (b) a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4-C10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer and wherein the polymer blend has a melt viscosity of 1,000 cP to 20,000 cP at 190° C.; (B) feeding one or more adhesive components, selected from at least one of a tackifier, wax, antioxidant, functionalized polyolefin, oil, and combinations thereof, into the extruder; and (C) recovering an extrudate from the extruder, wherein the extrudate is a hot melt adhesive composition.
    • 一种制备热熔粘合剂组合物的方法,包括(A)将聚合物共混物进料到挤出机中; 其中所述聚合物共混物包含(a)第一丙烯类聚合物,其中所述第一丙烯类聚合物是丙烯的均聚物或丙烯与乙烯或C 4 -C 10α-烯烃的共聚物; 和(b)第二丙烯类聚合物,其中所述第二丙烯类聚合物是丙烯均聚物或丙烯与乙烯或C 4 -C 10α-烯烃的共聚物; 其中所述第二丙烯类聚合物不同于所述第一丙烯类聚合物,并且其中所述聚合物共混物在190℃下的熔融粘度为1,000cP至20,000cP; (B)将选自增粘剂,蜡,抗氧化剂,官能化聚烯烃,油及其组合中的至少一种的一种或多种粘合剂组分进料到挤出机中; 和(C)从挤出机中回收挤出物,其中挤出物是热熔粘合剂组合物。
