 collapse point
 The synthesized networks formed a dense surface layer as the temperature increased past the gel collapse point. In DSC thermograms of swollen samples, the shape and onset temperature of the endothermic peak corresponded to the gel deswelling behavior and gel collapse point. In the interpenetrating polymer networks (IPN) system, the gel collapse point was not significantly changed by the amount of incorporated PTMEG. With increasing BMA content in the poly(NIPAAm-co-BMA) network, the gel collapse point was lowered and the gels deswelled in a more gradual manner with increasing temperature. Phys.79:1 (1995)], which excludes the existence of intermediate phases between the collapse point β=2 and the Kosterlitz-Thouless transition point βKT=4, is confirmed, however, a different analytic structure of this ansatz is suggested. 更多
