| titleOfInvention | Method for preparing long chain branched polylactic resin by combining two-step functional group reaction |
| abstract | The invention provides a method for preparing long chain branched polylactic resin by combining two-step functional group reaction, and relates to the technical field of polymer processing. The method for preparing the long chain branched polylactic resin by combining two-step functional group reaction comprises the following steps of: (1) melting polylactic resin; (2) adding an antioxidant, anhydride polyfunctional monomers and epoxy polyfunctional monomers, and mixing uniformly; and (3) melting and blending until the reaction is finished to obtain the long chain branched polylactic, wherein based on 100 weight parts of linear polylactic resin, the antioxidant is 0.1 to 0.5 part, the anhydride polyfunctional monomers are 0.1 to 1 part; and the epoxy polyfunctional monomers are 0.1 to 1 part; and the epoxy polyfunctional monomers have the functionality of more than or equal to 3. By the method, the reaction rate is improved by 5 to 10 times; the obtained long chain branched polylactic product has an obvious branching effect, the melt strength and viscosity are greatly improved, and the product material meets the requirement of forming and can be easily subjected to film making, foaming and other processes according to product requirements; and the branching degree and the melt strength of the product can be controlled to a certain extent by regulating a monomer proportion and reaction temperature. |
