    摘要: 1-butene based polymer satisfying following requirements (1null) to (4null) provides formed product having low stickiness, superior flexibility and transparency. (1null) Crystalline resin having melting point (TmnullP), not observed or in the range of 0 to 100null C., wherein said melting point defined as the peak top of the peak observed in the highest temperature zone of the melting heat absorption curve obtained by heating a sample of said polymer at a rate of 10null C./minute using Differential Scanning Calorimeter (DSC), after melting said sample in advance at 190null for 5 minutes under nitrogen atmosphere, followed by cooling it to null10null C. at a rate of 5null C./minutes, and keeping it at null10null C. for 5 minutes. (2null) Stereoregularity index null(mmmm)/(mmrrnullrmmr)null is at most 20. (3null) Molecular weight distribution (Mw/Mn) measured by Gel Permeation Chromatography (GPC) method is at most 4.0. (4null) Weight average molecular weight (Mw) measured by GPC method is in the range of 10,000 to 1,000,000.
