Abstract
A biodegradable resin composition and a method for producing the biodegradable resin composition are disclosed. The biodegradable resin includes three components, polyethylene, a biodegradable resin, and at least one selected from polybutylene adipate terephthalate and maleic anhydride copolymer, thereby providing excellent compatibility and mechanical properties.
Claims13
A biodegradable resin composition comprising a polyethylene in an amount of 50 wt % to 70 wt %, a biodegradable resin in an amount of 15-30 wt %, and a maleic anhydride copolymer in an amount of 10-30 wt %, each based on a total weight of the biodegradable resin composition,
- wherein the maleic anhydride copolymer is a copolymer of maleic anhydride with at least one selected from polybutylene adipate terephthalate (PBAT), polybutylene succinate adipate (PBSA), and polybutylene succinate (PBS).
A method for producing a biodegradable resin composition, said biodegradable resin composition comprising a polyethylene in an amount of 50 wt % to 70 wt %, a biodegradable resin in an amount of 15-30 wt %, and a maleic anhydride copolymer in an amount of 10-30 wt %, each based on a total weight of the biodegradable resin composition, wherein the maleic anhydride copolymer is a copolymer of maleic anhydride with at least one selected from polybutylene adipate terephthalate (PBAT), polybutylene succinate adipate (PBSA), and polybutylene succinate (PBS),
- the method comprising:
- providing a mixture of the polyethylene, the biodegradable resin, and the maleic anhydride copolymer, and subject to the mixture melt blending to produce the biodegradable resin composition.
