Polydisperse PA-oligo(PO-b-EO) allyl (methyl) ether siloxane surfactants [PA-oligo(PO-b-EO) and PA-oligo(PO-b-EO)Me series] were synthesized by the hydrosilylation reaction. To observe the thermal properties of the PA-oligo(PO-b-EO) allyl (methyl) ether siloxane surfactants, the phase transition temperature (cloud point: Cp) and weight-loss temperature were measured by using a thermal optical analyzer (TOA) and a thermal gravimetric analyzer (TGA). The values of the weight loss temperature and Cp of the PA-oligo(EO) and PA-oligo(EO)Me series increased upon increasing the EO chain length. Also, the weight-loss temperature of the PA-oligo(EO)Me series was higher than that of the PA-oligo(EO) series, and the values of Cp of the PA-oligo(EO)Me series were lower than those of the PA-oligo(EO) series because of the presence of the methoxy group (-OCH3). The values of Cp of the PA-oligo(PO-b-EO) and those of the PA-oligo(PO-b-EO)Me series decreased as the PO ratio, and the values of Cp of PA-oligo(PO-b-EO)Me were lower than those of the PA-oligo(PO-b-EO) series because of the existence of the methoxy group. However, the weight-loss temperature of the PA-oligo(PO-b-EO) and PA-oligo(PO-b-EO)Me series tended to increase with the PO ratio because the molecular weights of the PA-oligo(PO-b-EO) allyl (methyl) ether siloxane surfactants increased according to the increasing content of the PO unit.
