Kev tsim cov kua mem, cov tshuaj pleev xim, cov nplaum, cov tshuaj zas xim rau ntaub thiab cov tshuaj ua tiav, cov tshuaj pab tawv nqaij, cov tshuaj tiv thaiv dej thiab cov roj pleev, cov tshuaj tiv thaiv dej ntws, cov tshuaj ntxiv roj nplua nyeem, thiab cov tshuaj txo cov roj av viscosity.
1. Muaj ob qho kev ua haujlwm: Muaj ob qho tib si cov methacrylate thiab C18 long-saw alkyl bonds uas ua rau muaj kev sib txuas dawb thiab copolymerization nrog ntau yam monomers (xws li acrylates, styrene, acrylonitrile, thiab lwm yam) los muab cov haujlwm tshiab rau polymer.
2. Qhov kub hloov iav qis (Tg≈-100℃): Muab kev ywj pheej zoo heev rau qhov kub qis, tsim nyog rau cov ntaub ntawv tsim rau qhov chaw txias.
3. Qhov viscosity qis: Muaj kev ua haujlwm zoo thaum siv ua monomer, ua rau kev sib tov thiab kev tuav yooj yim.
4. Kev ruaj khov tshuaj lom neeg: Tiv taus hydrolysis, ua kom pom kev ruaj khov thermal zoo heev, nrog rau qhov kub txog li 192 ℃, ua kom muaj kev nyab xeeb zoo.
