Tetramethyl-6-decyne-5,8-diol polyoxyethylene: Their dynamic surface activity and dynamic spreading behavior in solutions

The dynamic surface activity in solutions, dynamic spreading on low energy surfaces of alkynol polyoxyethylene ether with two different units were evaluated by using the Wilhelmy-plate, maximum bubble pressure, contact angle method. The dynamic surface activity was depicted by using the classical Rosen model and the dynamic spreading was analyzed by decay function. The static contact angle (θe value) and spread rate (K value) should be taken into account in evaluating the effectiveness and efficiency of spread.
