| titleOfInvention | A kind of degradable polymer compositionss and preparation method thereof |
| abstract | The invention discloses a kind of degradable polymer compositionss, contain：Polymer and dispersion two or more transition metal salts in the polymer, wherein, at least one of described two above transition metal salts are multivalent transition metal salt.The invention also discloses the method preparing above-mentioned composition：Polymer is mixed with transition metal salt, is heated to molten condition, cooling shaping, obtains final product.The degradable polymer compositionss of the present invention, select two or more transition metal to produce cooperative effect.In cooperative effect phenomenon, multivalent transition metal plays the effect of catalyst to produce initiation free radical.When having high-energy after free radical is by UV light or thermal excitation, it will have enough energy and collective effect is to overcome the activated energy barrier of complicated polymer.Long chain will be fractured into small molecule.As a result, cooperative effect significantly promotes degradation process. |
