Taw qhia rau kev hloov kho tshuaj
Kev hloov tshuaj yog ib txoj kev ntawm kev hloov lub cev thiab tshuaj ntawm cov polymers los ntawm kev siv tshuaj lom neeg. Piv txwv li, ntu ntu ntawm polystyrene dhau lawm txhav dhau lawm, thiab cov ntu mos ntawm polyethylene tuaj yeem nkag tau los txhawm rau txhim kho kom tawv. Cov pab pawg kawg (amino, carboxyl, hydroxyl, thiab lwm yam) ntawm cov polymers xws li nylon thiab polyester tuaj yeem siv monobasic acids (benzoic acid lossis ethyl acetate). Acid anhydride), cov pa cawv monohydric cawv (cyclohexanol, butanol lossis benzyl cawv, thiab lwm yam) rau cov pab pawg xaus; alkyd polyesters tsim los ntawm polycondensation ntawm polyhydric cawv thiab polybasic kua qaub tsis muaj dej tsis zoo thiab tawv, thiab tuaj yeem hloov kho los ntawm kev ntxiv cov roj qaug zog Txhim kho nws cov dej noo tsis kam thiab dej tsis kam, thiab lub elasticity yog zoo dua qub.
