文摘

•: Hydrophilic properties of assayed polymers are proportional to the water absorption.
•: All assayed polymers enhanced water absorption at concentrations higher than 0.2%.
•: The mechanical strengths enhancing happened with acceleration of initial hydration.
•: The decrease of mechanical strengths happened with retard of the hydration.
