Hydroxypropyl methylcellulose, nke akụrụngwa cellulose, nwere ike nụchaa owu ma ọ bụ osisi pulp. Ọ dị ezigbo mkpa ịkụpịa ya tupu alkalization ma ọ bụ n'oge alkalization. Nchicha a bụ ibibi akụrụngwa cellulose site na ike igwe. Nhazi steeti mkpokọta nke cellulose macromolecules nwere ike belata ogo kristal na polymerization, na-abawanye mpaghara elu ya, si otú a na-emeziwanye ohere na ikike mmeghachi omume kemịkalụ nke mmeghachi omume reagent na otu hydroxyl atọ na mgbanaka glucose nke cellulose macromolecule.
Ọ bụ ezie na ụkpụrụ njikọ nke etherification nke hydroxypropyl methylcellulose adịghị mgbagwoju anya, gburugburu dị iche iche nke alkalization, ihe ọkụkụ na-echi ọnụ, etherification, mgbake mgbaze, nkewa centrifugal, ịsacha na ihicha gụnyere ọnụ ọgụgụ dị ukwuu nke teknụzụ isi na nkọwa ihe ọmụma bara ụba.
