Abstract
An object of the present invention is to provide a novel rotaxane and a production method of the same. The present invention provides a rotaxane polyurea having a cyclic molecule and a polyurea chain piercing through the cyclic molecule.
Claims21
A rotaxane polyurea having at least one cyclic molecule and a polyurea chain piercing through the cyclic molecule.
A method for producing a rotaxane polyurea, comprising carrying out a reaction between a rotaxane diamine that has a cyclic molecule and a diamine piercing through the cyclic molecule, and a diisocyanate capable of piercing through the cyclic molecule.
A method for producing a rotaxane polyurea, comprising carrying out a reaction of a rotaxane diamine that has a cyclic molecule and a diamine piercing through the cyclic molecule, a diisocyanate capable of piercing through the cyclic molecule, and a blocking compound that has two functional groups reactive with the rotaxane diamine or diisocyanate and blocks the cyclic molecule by steric hindrance, to form a polyurea chain piercing through the cyclic molecule.
