  • Thermo-sensitive cell culture substrate having block copolymer
    Patent number: 11505633
    Abstract: A method of preparing PNVCL block polymers as the substrate for thermo-sensitive cultureware is provided. A hydrophobic polymer of poly n-butyl mathacrylate (PBMA) is obtained by atom transfer radical polymerization (ATRP) with typical haloalkane as an initiator. Further a thermo-sensitive block copolymer of poly n-vinyl caprolactam (PNVCL) is obtained by polymerization of N-vinyl caprolactam (NVCL) monomers using the hydrophobic PBMA polymer as a macroinitiator.
    Type: Grant
