Title:

OLEFIN RESIN AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2015/147186

Kind Code:

A1

Abstract:

　Provided is an olefin resin having improved heat resistance and tackiness, as well as excellent optical characteristics and low-temperature characteristics, and an enhanced balance of these properties. This olefin resin satisfies conditions (I) through (V). (I) The olefin resin exhibits a melting peak (Tm) in the range of 60°C to 130°C, and the heat of fusion (∆H) at the melting peak is 5 to 150 J/g. (II) The ratio (E) (wt%) of orthodichlorobenzene-soluble components at 20°C or below and the heat of fusion (∆H) satisfy a specific relationship. (III) The glass transition temperature (Tg) is -80 to -30°C. (IV) The spin-spin relaxation time (T2) of the most dynamic component for a four-component approximation of a free induction decay curve is in the range of 150 to 500 ms, and the abundance ratio of the component is in the range of 15 to 50%. (V) The limiting viscosity measured in decalin at 135°C is 0.1 to 12 dl/g.
