Ngwaahịa Hydroxypropyl Methyl Cellulose nwere oke oriri na mpaghara polymerization nke vinyl chloride na China. Na polymerization nke vinyl chloride, sistemụ agbasasị nwere mmetụta kpọmkwem na ngwaahịa ahụ, resin PVC, yana na mma nke nhazi ya na ngwaahịa ya. HydroxypropylMethylCellulose na-enyere aka imeziwanye nkwụsi ike okpomọkụ nke resin ma chịkwaa nkesa nha ihe dị n'ime ya..Resin PVC nke e ji HydroxypropylMethylCellulose dị elu mee abụghị naanị na ọ nwere ike ime ka usoro arụmọrụ ya kwekọọ na ọkọlọtọ mba ụwa, kamakwa ọ nwere ike inwe ezigbo ihe onwunwe anụ ahụ, ihe onwunwe dị mma na àgwà rheological dị mma.
N'imepụta resin sịntetik, dịka polyvinyl chloride, polyvinylidene chloride, na copolymers ndị ọzọ, polymerization nke nkwụsịtụ bụ nke a na-ejikarị eme ihe ma ga-abụrịrị monomers hydrophobic na-adịghị agbanwe agbanwe nke a kwụnyere na mmiri. Dịka polymers mmiri na-agbaze, ngwaahịa HydroxypropylMethylCellulose nwere ọrụ dị mma n'elu ma na-arụ ọrụ dị ka ihe nchebe colloidal. HydroxypropylMethylCellulose nwere ike igbochi ihe polymeric nke ọma imepụta na ịchịkọta. Ọzọkwa, ọ bụ ezie na HydroxypropylMethylCellulose bụ polymer mmiri na-agbaze, ọ nwere ike ịgbaze ntakịrị na monomers hydrophobic ma nwee ike ịbawanye porosity monomer maka mmepụta nke ihe polymeric.
Na mgbakwunye, ọmụmụ ihe egosila na n'usoro mmepụta nke PVC, ụlọ ọrụ dị iche iche na-eji sistemụ dị iche iche agbasasị, yabụ njirimara mkpuchi mpụta nke PVC emepụtara dịkwa iche, yabụ HydroxypropylMethylCellulose nwere ike imetụta arụmọrụ nhazi nke resin PVC. Na sistemụ ihe na-ekesa ihe mejupụtara, resin PVC nke a kwadebere site na ihe na-agbasa ihe mejupụtara nke polyvinyl alcohol (PVA) nwere ogo alcoholism na polymerization dị iche iche na hydroxypropyl methyl cellulose (HPMC) nwere ike inwe mmetụta dị iche iche na arụmọrụ nhazi. Nnwale egosila na ngwakọta nke HydroxypropylMethylCellulose na KP-08/KZ-04 nwere ogo alcoholization nke 68% -75% ka mma ma baa uru maka porosity nke resin na nnabata nke plasticizers.
