Cov yam ntxwv ntawm rubbery lub xeev
Lub sijhawm no, thaum cov polymer ua nrawm thiab thau khoom tawm, nws txoj kev hloov pauv hloov tuaj yeem ncav cuag 500 ~ 1000%, thiab cov kev ua rov qab sai sai tuaj yeem muab qee yam nyob rau hauv cov xov hluav taws xob ntev ntev-polymer linear polymer, yog li nws muaj fluidity; cov kab sib txuas ua ke polymer vim cov roj molecular saw Cov nyhuv tshuaj lom neeg sib txuas ua ke tsis tuaj yeem ntws. Lub siab elasticity yog qhov tshwj xeeb txhua yam tshuab ntawm polymers.
