    • PURPOSE: Provided are a polybutene resin excellent in high-speed moldability as well as creep resistance and pressure resistance, and a pipe material and a pipe comprising the same. CONSTITUTION: The polybutene resin is characterized by: (1) comprising 80 to 100 mol% of the 1-butene unit and 0 to 20 mol% of a C2-10 alpha -olefin (except 1-butene) unit; (2) having a melt flow rate (MFR) of 0.01 to 10 g/10 minutes; (3) having a molecular weight distribution represented by the ratio (Mw/Mn) of a weight-average molecular weight (Mw) to a number-average molecular weight (Mn) of 6 or larger; and (4) in a molecular weight distribution curve plotted on the basis of a chromatograph by gel permeation chromatography (GPC), the portion of weight-average molecular weights of 6 x10 or higher accounting for 20% or larger of the total area, which is defined as the area surrounded with the curve and the horizontal axis.
    • 目的:提供高速成型性以及耐蠕变性和耐压性优异的聚丁烯树脂,以及管材和包含该聚丁烯的管。 构成:聚丁烯树脂的特征在于:(1)包含80-100mol%的1-丁烯单元和0-20mol%的C 2-10α-烯烃(除1-丁烯)单元; (2)熔体流动速率(MFR)为0.01〜10g / 10分钟; (3)具有以重均分子量(Mw)与数均分子量(Mn)的比(Mw / Mn)为6以上的分子量分布表示的分子量分布; 和(4)在基于通过凝胶渗透色谱(GPC)的色谱仪绘制的分子量分布曲线中,重均分子量为6×10以上占部分总面积的20%以上,其中 被定义为用曲线和水平轴包围的区域。
