、あるいはエチレンが共重合されていても高々５％程度
であるため、これらの生産時に副生されるアタクチック
ポリプロピレンもエチレンが高々５〜６％程度である。[Prior Art and Problems] Conventionally, low viscosity hot melt adhesives based on atactic polypropylene have been widely used. This atactic polypropylene is a low-molecular-weight amorphous polymer that is produced as a by-product during the production of crystalline isotactic polypropylene resin, and is inexpensive because it has a low viscosity and is a by-product residue of crystalline polypropylene. It has been used in melt adhesives. However, the currently available crystalline isotactic polypropylene is
There are three types of polymers: homopolymers, random copolymers, and block copolymers, but the composition consists of propylene alone or even if ethylene is copolymerized, it only accounts for about 5% at most, so it is produced as a by-product during their production. Atactic polypropylene also contains about 5 to 6% ethylene at most.
このようにプロピレンが主成分であるため、低温特性が
悪かった。また、副生の残渣であるため、軟化点。Since propylene was the main component, the low-temperature properties were poor. Also, since it is a by-product residue, it has a softening point.

際に溶媒を用いるため、溶媒も残存する欠点がある。Properties such as hardness are not constant, and the molecular weight of the by-product atactic polypropylene changes depending on the molecular weight of the isotactic polypropylene, so the melt viscosity is also not constant, catalyst residue etc. are present, and isotactic Since a solvent is used when separating 7-tactic polypropylene from polypropylene, there is a drawback that the solvent also remains.
上記の欠点を持ったアタクチックポリプロピレンを主成

のである。In other words, the present invention can be used as a hot melt adhesive that maintains heat resistance, does not peel off or reduce strength at low temperatures, has no odor or risk of ignition, and has stable qualities such as softening point and melt viscosity. It is intended to provide the following.

量が８〜３０重量％の非晶性ランダム共重合体である。The amorphous propylene/ethylene random copolymer used in the present invention is purpose-produced. For example, ethylene is added to liquefied propylene in the presence of hydrogen using a titanium-supported catalyst supported on magnesium chloride and triethylaluminum. It is an amorphous random copolymer with a number average molecular weight in the range of i,ooo to 20,000 and an ethylene content of 8 to 30% by weight.

の問題もない。Compared to by-product atactic polypropylene, this polymer is produced for a specific purpose, so its properties such as softening point and melt viscosity are of stable quality within a certain range. Furthermore, the softening point and melt viscosity can be set to constant values by adjusting the copolymerization ratio and molecular weight of propylene and ethylene. Furthermore, since it is a polymer that does not use a solvent, there is no risk of ignition or odor problems.

着剤としての凝集力が低く、高温耐熱用途に向けること
ができない。If the number average molecular weight of the amorphous propylene/ethylene random copolymer is less than 1.000, the cohesive force is too low to obtain sufficient adhesive strength, and if it is 20.000 or more, the melt viscosity is too low. If it is too high, there are problems with workability, and the difference in viscosity from other blending purposes is large, making blending difficult, and lack of fluidity makes uniform application difficult. Those containing less than 8% by weight of ethylene have poor low-temperature properties and poor compatibility with ethylene resins. Moreover, if it is more than 30% by weight, it becomes soft at room temperature and has a lower softening point, so it has low cohesive strength as an adhesive and cannot be used for high-temperature heat-resistant applications.
