Abstract
Described herein are block copolymers that can be used as compatibilizers. The block copolymers can be graft block or triblock copolymers. The block copolymers can include a polysaccharide or a polyester and a polyolefin. Also described herein are polymer blends that can include and be made using the block copolymers described herein.
Claims20
An ABA triblock copolymer comprising:
- a polysaccharide, wherein the polysaccharide is the A block polymer;
- and
- a polyolefin, wherein the polyolefin is the B block polymer.
A polymer blend comprising:
- a compatibilizer, wherein the compatibilizer is an ABA triblock copolymer,
- wherein the ABA triblock copolymer comprises a polysaccharide, wherein the polysaccharide is the A block polymer;
- and a polyolefin, wherein the polyolefin is the B block polymer.
A method of making a polymer blend, the method comprising:
- compatibilizing a polysaccharide and a polyolefin with an ABA triblock,
- wherein the ABA triblock copolymer comprises a polysaccharide, wherein the polysaccharide is the A block polymer;
- and a polyolefin, wherein the polyolefin is the B block polymer.
