He whānuitia ngā whakamahinga o te Methyl methacrylate (MMA):

‌Whakamahinga matua‌: Hei monomer o te karāhe waro (polymethylmethacrylate, PMMA), e whakamahia ana hei hanga kirihou mārama‌.
‌Ētahi atu kirihou me ngā paninga‌: Whakamahia hei hanga i ētahi atu kapia, kirihou, me ngā paninga, hei whakarato i ngā rauemi mata matua mō ēnei ahumahi‌.
‌He maha ngā whakamahinga ahumahi‌: Hei hinu whakahinuhinu, hei whakakī i te rakau me te kōka, hei whakakī i te koiri motuka, hei whakakanapa pepa, hei tāpiri tae me te tā kakahu, hei rongoā hiako me te whakakī whakamahana, me ētahi atu, he whānuitia te whakamahinga i roto i ngā mara ahumahi maha‌.
‌Waenga patu harore‌: Hei takawaenga o te patu harore Sclerotium, e whakamahia ana i roto i te hanga patu harore‌.
He matū mata nui te methyl methacrylate. Ka taea e tōna kohu me te hau te hanga i tētahi ranunga pahū. Kia tūpato ki te haumaru i te wā e whakamahia ana‌4. Ehara i te mea he mahi nui tana i roto i te umanga kirihou me te paninga anake, engari he mahi nui anō hoki i roto i te maha atu o ngā mara.

He āhuatanga motuhake tō ia tikanga, tō ia tikanga, ā, ka taea te whiriwhiri i ngā huarahi hanga e tika ana kia rite ki ngā hiahia me ngā āhuatanga motuhake.

Ko ngā tikanga whakarite mō te methyl methacrylate (MMA) ko ngā mea e whai ake nei:

Tikanga Acetone cyanohydrin: Whakamahia te acetone hei rauemi mata, ka tauhohe tuatahi ki te waikawa hydrocyanic hei whakaputa i te acetone cyanohydrin, kātahi ka whakamahanahia ki te waikawa whanariki kukū me te methanol hei mahi i te hydrolysis, te dehydration me te esterification hei whakarite i te MMA. He tikanga noa tēnei mō te whakaputa MMA. Kua pakari te hangarau, engari he tino paitini te rauemi mata, arā, te waikawa hydrocyanic, ā, he uaua ki te rongoā i ngā para e toru.
Tikanga Isobutylene: Ka whakapūngaohia te Isobutylene ki te methacrolein me te hau i te aroaro o tētahi whakakorikori, kātahi ka whakapūngaohia ki te waikawa methacrylic, ā, i te mutunga ka whakapūngaohia ki te methanol hei whiwhi i te MMA. He tukanga whakapūngao kotahi-taahiraa anō hoki e whakapūngao tika ana hei whakaputa i te waikawa methacrylic, kātahi ka whakapūngaohia.
‌Te ara o te propylene: Mā te tauhohenga warohanga o te propylene, te hauota waro me te methanol ka puta te 2-methoxyisobutyric acid methyl ester, ka pakaru hei MMA me te methanol i muri i te waikura.
