1：Experimental Design and Method Selection:

The study involved ring-opening metathesis copolymerization (ROMP) of HBM with ester-functionalized comonomers (NMA, NME, NMD) using Grubbs first generation catalyst (G1), followed by hydrogenation. This method was chosen for its tolerance to functional groups and ability to produce well-defined polymers.

2：Sample Selection and Data Sources:

Monomers HBM, NMA, NME, and NMD were synthesized or obtained from suppliers. Copolymers were prepared with varying feed ratios to study composition effects.

3：List of Experimental Equipment and Materials:

Equipment included Schlenk techniques, glovebox, NMR spectrometer, FT-IR spectrometer, DSC, GPC, TGA, tensile testing machine, contact angle goniometer, UV-Vis spectrophotometer, XPS. Materials included solvents (dichloromethane, toluene, methanol), catalysts (G1), hydrogenation agents (4-methylbenzenesulfonhydrazide), and monomers.

4：Experimental Procedures and Operational Workflow:

Polymerization was conducted in dichloromethane at room temperature with G1 catalyst, followed by hydrogenation using toluenesulfonyl hydrazide. Polymers were precipitated, washed, and dried. Films were cast from tetrachloroethane solutions. Characterization involved NMR, FT-IR, DSC, GPC, TGA, tensile tests, contact angle measurements, UV-Vis, and XPS.

5：Data Analysis Methods:

Data were analyzed using NMR for composition, GPC for molecular weights, DSC for Tg, TGA for thermal stability, tensile tests for mechanical properties, and statistical methods for reactivity ratios (Fineman-Ross method).
