With the stress of solid phase stress

the polymer molecule structure would be weakened or destroyed

and the chemical bonds may be distorted or broken.Polymers of solid phase chemical modification are used to study the physical and chemical changes of various polymers

which occur duing to mechanical effect.As the method has wide applicability

purity product

ease of operation

high efficiency

easy

saving energy

no pollution and so on

it becomes one of the important methods of polymer modified.This ariticle systematically review the mechanism and methods of the solid state shear pulverization of polymer

polymer solid-phase disc-type milling grinding

crushing mechanism of polymers and high-energy ball milling

detailly describe technology progress of these types of grinding methods on the application of polymer modified

and indicate the stress on the theory and trends in the application of key technology of solid-phase chemical modification of polymer.
