Ntshiab kua. Acetoacetoxyethyl Methacrylate [21282- 97-3], AAEM, muaj cov pendant acetoacetoxyethyl pawg uas tuaj yeem hloov kho lub cev ntawm acrylic polymers los ntawm kev txo cov tshuaj viscosity thiab txo cov iav hloov pauv kub. Tsis tas li ntawd, pawg acetoacetyl muaj cov active methylene pab pawg neeg thiab carbonyl pawg, uas yuav siv tau los hloov kho los yog cross-links cov polymer [107]. |
| Siv |
LONZAMON(R) AAEMA yog ib qho tshwj xeeb methacrylic ester monomer nrog ib pawg methylene reactive. Nws yog tsim raws li comonomer rau cov nplaum thiab coatings nrog rau copolymer rau emulsion polymerization. |
| Siv |
2-(Methacryloyloxy)ethyl acetoacetate yog methylene active compound uas tej zaum yuav siv tau nyob rau hauv lub synthesis ntawm 2-(methacryloyloxy)ethyl 6-methyl-2-oxo-4-phenyl -1,2,3,4- tetrahydropyrimidine-5-carboxylate. Nws tuaj yeem siv los ua tus neeg sawv cev polymerizable chelating rau cov hlau alkoxides los ua polymerizable oxide precursors. |

| Hom kev ua |
Lub sol-gel polymerization ntawm Si Ti Zr sols yog qhov nthuav vim tias muaj peev xwm tswj tau ntau yam khoom xws li qhov ntsuas qhov cuam tshuam, thermal expansion coefficient, thiab kev tiv thaiv alkaline corrosion nres hauv cov khoom kawg (xws li, cov khoom siv kho qhov muag, photonics, sensors, thiab catalysts). Txoj kev polymerization tuaj yeem raug coj mus rau kev tsim cov hybrid organic-inorganic system uas siv cov tshuaj hloov kho xws li 2-(methacryloyloxy) ethyl acetoacetate (MEEAH), uas tuaj yeem ua raws li bidentate (bridging lossis chelating) tus neeg sawv cev thiab muaj. Qhov ua tau ntawm cov organically polymerizable vim muaj cov tsis muaj CC daim ntawv cog lus hauv cov molecule. Lub xub ntiag ntawm CC daim ntawv cog lus hauv MEEAH tau tso cai ua haujlwm ib txhij ntawm cov organic thiab inorganic polymerization thaum tuav lub homogeneity ntawm sols thiab gels. Hais txog tus nqi ib nrab nqi, nyob rau hauv txhua rooj plaub, δ (MEEA?) yog qhov tsis zoo, qhia tias nws tuaj yeem yooj yim khi Ti thiab Zr. Ntawm qhov tod tes, δ (OPrn) thiab δ (OPri) qhov tseem ceeb yog qhov zoo hauv txhua lub molecules qhov twg MEEA? kuj muaj, thiab yog li ntawd cov hom (OPrn thiab OPri) yog labile[1]. |
