摘要： The present invention relates to a method of preparing a polyrotaxane, said method comprising: performing a radical copolymerization of at least (a) a first polymerizable monomer having a stopper group, and of at least (b) a second polymerizable monomer, wherein said second monomer is complexed by a ring-shaped molecule; wherein during said copolymerization a copolymer threading said ring-shaped molecule is formed, wherein during said copolymerization said first monomer having a stopper group is incorporated into the chain of said copolymer at least partially between the ends thereof, and wherein said stopper groups prevent said ring-shaped molecule from disassembling from the copolymer; and wherein the amount of said first monomer having a stopper group is of from 0.1 mol % to 20 mol % based on 100 mol % of the total amount of polymerizable monomers. The present invention also relates to polyrotaxanes which can be prepared by using such a method. The present invention further relates to cross-linked polyrotaxanes, products which contain polyrotaxanes or cross-linked polyrotaxanes or which can be prepared from polyrotaxanes or cross- linked polyrotaxanes, and the use of polyrotaxanes or cross-linked polyrotaxanes.

摘要： In one embodiment the invention relates to a method of preparing a polyrotaxane, said method comprising: performing a radical copolymerization of at least (a) a first polymerizable monomer having a stopper group, and of at least (b) a second polymerizable hydrophobic monomer, wherein said second monomer is complexed by a ring-shaped molecule, and of at least (c) a third polymerizable hydrophilic monomer; wherein during said copolymerization a copolymer threading said ring-shaped molecule is formed, wherein during said copolymerization said first monomer having a stopper group is incorporated into the chain of said copolymer at least partially between the ends thereof, and wherein said stopper groups prevent said ring-shaped molecule from disassembling from the copolymer; and wherein the amount of said first monomer having a stopper group is of from 0.1 mol % to 20 mol % based on 100 mol % of the total amount of polymerizable monomers. In another embodiment the invention relates to a method of preparing a polyrotaxane, said method comprising: performing a radical copolymerization of at least (a) a first polymerizable monomer having a stopper group, and of at least (b) a second polymerizable partially hydrophilic monomer, wherein said second monomer is complexed by a ring-shaped molecule, and wherein said second monomer has a solubility in water at 20°C of from 5 g/L to 40 g/L; wherein during said copolymerization a copolymer threading said ring-shaped molecule is formed, wherein during said copolymerization said first monomer having a stopper group is incorporated into the chain of said copolymer at least partially between the ends thereof, and wherein said stopper groups prevent said ring-shaped molecule from disassembling from the copolymer; and wherein the amount of said first monomer having a stopper group is of from 0.1 mol % to 20 mol % based on 100 mol % of the total amount of polymerizable monomers. Furthermore, the present invention relates to methods of preparing cross-linked polyrotaxanes and cross-linked polyrotaxanes which can be prepared using such methods. Thus, the present invention also relates to polyrotaxane and crosslinked polyrotaxanes. The invention also relates to products which contain the polyrotaxanes or cross- linked polyrotaxanes or which can be prepared from the polyrotaxanes or the cross-linked polyrotaxanes. The present invention further relates to the use of polyrotaxanes or cross-linked polyrotaxanes in various applications, such as the use as a self-healing material.
