In some cases.
- the low molecular weight polymer since it is more difficult to crystallize as an ultra-high molecular weight body, it is possible that the wide shape on the low temperature side in the DSC measurement method is due to the ultra-high molecular weight body. Further, when the polymer spreads to the low molecular weight side, the low molecular weight polymer generally has a high crystallinity, but tends to have a low heat of fusion. Therefore, ⁇ H measured as heat of fusion (heat of crystallization) may also tend to be low.

- the propylene-based polymer of the present invention tends to have a high melting point, but tends to show a shape that gently extends to a higher temperature side. That is, since it is suggested that there is a polymer that is difficult to melt even in a high temperature region, it is highly possible that the polymer has high heat resistance. The reason for exhibiting such a feature is unknown, but the present inventors speculate as follows.
- the propylene polymer of the present invention has a high content of the super high molecular weight polymer, and the super high molecular weight polymer has a higher steric regularity than the conventional propylene polymer, so that it is easy to crystallize.
- the ultra-high molecular weight polymer also functions as a crystallization nucleating agent, and polymers in a higher molecular weight region (a region that tends to be difficult to crystallize due to decreased molecular motility) can be easily crystallized. It is considered that the phenomenon of heat of fusion based on crystals is also observed on the high temperature side as described above.

On the other hand, if the lower limit of Tm-maxv is higher than the above value, a high temperature is required for melting and flowing, and a large amount of energy (calorific value) may be required at the time of molding.

That is, the heat resistance may be insufficient. It is also possible that it is difficult to function as a crystallization nucleating agent.
- Mw is a weight average molecular weight and Mn is a number average molecular weight.

(2)メルトフローレート(MFR):
ASTM D1238Eに準拠し、測定温度はプロピレン重合体の場合、230℃とした。
ガラス製の測定容器にプロピレン重合体約3グラム(10-4グラムの単位まで測定した。また、この重量を、下式においてb(グラム)と表した。)、デカン500ml、およびデカンに可溶な耐熱安定剤を少量装入し、窒素雰囲気下、スターラーで攪拌しながら2時間で150℃に昇温してプロピレン重合体を溶解させ、150℃で2時間保持した後、8時間かけて23℃まで徐冷した。得られたプロピレン重合体の析出物を含む液を、磐田ガラス社製25G-4規格のグラスフィルターにて減圧濾過した。濾液の100mlを採取し、これを減圧乾燥してデカン可溶成分の一部を得て、この重量を10-4グラムの単位まで測定した(この重量を、下式においてa(グラム)と表した。)。この操作の後、デカン可溶成分量を下記式によって決定した。

の条件で測定し、得られたクロマトグラムを公知の方法によって解析することで重量平均分子量(Mw)、数平均分子量(Mn)、Z平均分子量(Mz)、および分子量分布(MWD)の指標であるMw/Mn値、Mz/Mw値を算出した。1サンプル当たりの測定時間は60分であった。
本発明における重合体の融点(Tm)、結晶化温度(Tc)、融解熱量(ΔH)は、パーキンエルマー社製DSC8000装置で示差走査熱量計(DSC)により測定した。試料3~10mgをアルミニウムパン中に密封し、室温から100℃/分で200℃まで加熱した。その試料を、200℃で5分間保持し、次いで10℃/分で30℃まで冷却した。この冷却試験で、ピーク温度を結晶化温度(Tc)とした。続いて30℃で5分間置いた後、その試料を10℃/分で200℃まで2度目に加熱した。この2度目の加熱試験で、ピーク温度を融点(Tm)、吸熱量を融解熱量(ΔH)として採用した。また、融解熱量として、前記冷却(降温)時の発熱量も融解熱量(ΔH)として併記した。
前記2度目の加熱試験の工程で、吸熱曲線とベースラインとの交点の最も高い温度を上記の指標とした。この指標は、例えば超高分子量重合体が高結晶化していることに起因すると考えることができる。超高分子量重合体成分は、分子鎖の動きが遅いため、その成分の結晶性が高い程、DSC測定では高温でも吸熱ピークを示すと考えられることから、本発明ではこの指標を用いている。
上記(6)での吸熱ピークが終息する領域での吸熱曲線の接線を常法のデータ処理方法で作成し、その接線とベースラインとの交点を上記温度とした。吸熱ピークがなだらかな形状程、この温度は高くなる傾向がある。前記のような形状は、例えば高結晶化した超高分子量体が多いことに起因すると考えることができる。
