    Abstract: Packaging and/or storing atactic polypropylene or other amorphous poly alpha olefins is accomplished by first heating a mass of the olefin material to a molten state and then cooling the molten mass of olefin material to an extrusion temperature. Next, the formless mass of atactic polypropylene is extruded and cut into a succession of pellets. Inert dust-like material is sprayed onto the cutting surfaces and the surface of the olefin material so that the natural tendency of the material to stick to itself and to other objects is avoided.

    Abstract translation: 通过首先将大量烯烃材料加热至熔融状态,然后将烯烃材料的熔融物质冷却至挤出温度来实现包装和/或储存无规聚丙烯或其它无定形聚α-烯烃。 接下来,将无形质量的无规立构聚丙烯挤出并切割成一系列颗粒。 将惰性的粉尘状材料喷涂到切割表面和烯烃材料的表面上,从而避免了材料自身粘附到其它物体的自然倾向。

    Abstract: A hot melt adhesive formulation includes 60 to 99 wt. % of an amorphous propylene-co-hexene-1 polymer component based on the total weight of the hot melt adhesive without the use of flammable solvents, 20 to 80 wt % of hexene-1 co-monomer based on the total weight of the amorphous propylene-co-hexene-1 copolymer component, 20 to 80 wt. % of a propylene co-monomer based on the total weight of the amorphous propylene-co-hexene-1 copolymer component, and from 1 to 40 wt. % of a co-adjuvant based on the total weight of the hot melt adhesive. The hot melt adhesive formulation has rolling ball tack from 2 to 50 centimeters at ambient temperature after conditioning at ambient temperatures for 24 hours. The hexene-1 monomer to propylene monomer ratios are from 4:1 to 1:4.
