| Itaconic acid Siv thiab Synthesis |
| Chemical Properties | dawb mus rau lub teeb beige crystalline hmoov |
| Siv | Copolymerizations, resins, plasticizers, lube-roj additive, nruab nrab. |
| Siv | Kev siv loj rau itaconic acid yog nyob rau hauv copolymerizations, resins, plasticizers, thiab li roj additives. |
| Siv | Itaconic acid yog siv rau hauv kev npaj ntawm acrylonitrile-butadiene-styrene thiab acrylate latexes. Nws kuj yog siv los npaj poly-itaconic acid, resins biofuel Cheebtsam thiab ionomer cements. Nws pom daim ntawv thov nyob rau hauv textile, tshuaj thiab tshuaj industries. Nws kuj yog siv los ua ib qho additive nyob rau hauv fibers thiab ion pauv resins kom abrasion, waterproofing, lub cev tsis kam, tuag affinity thiab zoo lub sij hawm. Tsis tas li ntawd, nws ua raws li ib tug co-monomer siv nyob rau hauv kev npaj ntawm acrylic fibers thiab rubbers, reinforced iav fiber, dag pob zeb diamond thiab lens. Nyob rau hauv tas li ntawd, nws ua raws li ib tug binder thiab sizing tus neeg saib xyuas nyob rau hauv tsis-woven fibers. |
