康奈尔 large R&D new type catalytic agent can improvement recycling plastics performance!
plastics recycling has large difficult 题, separation is classification and separation 离. ratio food packaging bag has more packaging film （BOPET/PE or 者PA6/PE composite/compounding and other ）, method different formed packaging film separation 离, classification recycling is large difficult 题.
has can can full recycling, can 吗? 不行! different polymer/macromolecule property can different, 会导致 versus separation 离, recycling to material property can decline. Japan versus 安倍晋三也呼吁 “勿敌视 plastics, tube/pipe and new is key/critical ”.
therefore in packaging industry, 一方面希望 through mono separation achieve more function is development trend. for/regarding recycling industry 说: can can separation 离, mixed mixed, add 点 increase solvent agent type achieve recycling plastics high value utilizing 呢?
USA 康奈尔 large 学Coates课题组 long force 于烯烃 active property polymerization research, 他们希望 through development tool has long catalytic lifespan catalytic agent made polymer/macromolecule amount polyethylene (PE) / full polypropylene (PP) or more copolymer.
吡啶 amine Hf catalytic agent in high temperature lower can made polymer/macromolecule amount full polypropylene (PP) (Angew. Chem. Int. Ed. 45, 3278–3283 (2006)) meanwhile by used for “链穿梭” polymerization (Science 312, 714–719 (2006).).
2008 year, Coates课题组报道 optimization rear amine Hf catalytic agent (I) can achieve for/regarding propylene full can polymerization (Patent WO2008112133A2 (2008)).
2017 year, Coates课题组报道 use catalytic agent made tool has long degree can ethylene / full polypropylene (PP) and more copolymer.
this category of new copolymer and polyethylene (PE) / full polypropylene (PP) tool has good interface property can, can good improvement recycling plastics property can to high value polymer/macromolecule material.
而 in PET:PE（80:20） mixed combined material in add 0.5wt% PET-PE more 嵌段链, to PET/PE blending material fracture force and ultra- pure PET, achieve waste plastics PET and PE high value utilizing, this formed obtain 《Science》 editor recommendation.
引 use Japan versus 安倍晋三 话: 勿敌视 plastics, tube/pipe and new is key/critical.
