Abstract
The present invention discloses a waterproof and gas permeable material containing polyurethane with hydrophilic side chain. The mentioned waterproof and gas permeable material comprises a polyurethane main chain and a hydrophilic side chain, wherein the main chain further comprises a hard segment and a soft segment. The hard segment is formed by reacting biisocyanate and chain extender, and the soft segment is formed from polyols. Additionally, one side of the hydrophilic side chain is bonded to the main chain, and another side acts freely.
