Title:
LACTIC ACID-BASED RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2006052343
Kind Code:
A
Abstract:
To obtain a resin composition that has biodegradability and excellent heat resistance, especially elastic properties in a high-temperature environment.
The resin composition is obtained by mixing 100 parts by mass of a lactic acid-based resin with 10-100 parts by mass of a rosin derivative. The rosin derivative has 100°C-170°C softening temperature. A polymerized rosin ester or a rosin-modified phenol resin is used as the rosin derivative. The resin molding composed of the resin composition has ≥10MPa storage elastic modulus at 80°C.
