The formation of polyrotaxanes of type 1 by “statistical” threading 1 will be described. Examples will include polymerization in the presence of macrocycles and threading of preformed polymers and macrocycles. An analysis of the structural and experimental factors involved in the threading process will be presented. The solution and solid state behavior of the polyrotaxanes will be discussed, including situations in which T g can be controlled by macrocycles that are compatible with the backbone and situations where the threaded macrocycles crystallize. The preparation of polyrotaxanes of type 3 by threading of polymacrocycles 2 with linear polymers and the resultant changes in physical properties will also be described.
