Title:
ADHESIVE COMPOSITION AND ADHESIVE TAPE USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/069604
Kind Code:
A1
Abstract:
Provided are: an adhesive composition that, using a polyolefin polymer, has high adhesive strength and holding strength and does not leave behind residual glue; and an adhesive tape using the adhesive composition. The adhesive composition contains: (1) 5-95 mass% of a polyolefin having a ΔH of less than 5 J/g and a melting point that is not observed by means of differential scanning calorimetry (DSC) or that is less than 20°C; and (2) 5-95 mass% of a polyolefin having a ΔH of 5-100 J/g inclusive and a melting point of 20-160°C inclusive. The storage elastic modulus of the composition at 25°C obtained from a solid viscoelastic measurement is 1-200 MPa inclusive, and the storage elastic modulus at 50°C is 1-100 MPa inclusive.
