The purpose of the present invention is to provide a dynamically cross-linked polymer with temperature-responsive properties. The problem is solved by a recombination method of dynamic cross-linked compounds with a basic skeleton of the invention's diamino polysulfide, which involves a cleavage step of breaking the sulfur-sulfur bonds between the dynamic cross-linked compounds by heating to obtain cleaved dynamic cross-linked compounds, and a step of cooling the cleaved dynamic cross-linked compounds to combine the sulfur radicals of the two cleaved dynamic cross-linked compounds.
A Strategy toward Cyclic Topologies Based on the Dynamic Behavior of a Bis(hindered amino)disulfide Linker
structures has been developed based on the dynamic behavior of the linker bis(2,2,6,6-tetramethylpiperidin-1-yl)disulfide (BiTEMPS). The prime linear structure was transformed into a (macro)cycle using the following sequence: 1) thiol-ene reaction with a BiTEMPS derivative to afford the linear precursor, then 2) an entropy-driven transformation induced by diluting and heating. The radicals generated from BiTEMPS
