PHB / PEN / PET three component liquid crystal polymer blend

摘要

1. The technical field to which the invention described in the claims belongs;The present invention relates to a liquid crystal polymer blend produced by mechanically blending a thermotropic liquid crystal polymer (TLCP) and a polyester-based polymer.;2. Technical Problems to be Solved by the Invention;A mixture of thermotropic liquid crystalline polymer (TLCP) and PET (polyethylene terephthalate) on PEN (polyethylene 2,6-naphthalate) with similar properties as the thermotropic liquid crystal polymer prepared by monomer polymerization And a liquid crystal polymer blend having good processability.;3. The point of the solution of the invention;The present invention is accomplished by mechanically blending TLCP (thermotropic liquid crystal polymer), which is a copolymer of PHB (parahydroxybenzoic acid) and PET, and PEN and PET. At this time, the weight fraction of PHB in the blend is 30% to 70%, and the ester interchange reaction occurs between the compositions by the mechanical blending.;4. Important Uses of the Invention;By providing a liquid phase PHB / PEN / PET three component blend with a minimum PHB content, a high-strength advanced material can be produced at a low cost.
