Ngwaahịa Hydroxypropyl Methyl Cellulose nwere oke oriri na mpaghara nkwusioru polymerization nke vinyl chloride na China.Na nkwusioru polymerization nke vinyl chloride, usoro a chụsasịrị nwere mmetụta kpọmkwem na ngwaahịa, PVC resin, na àgwà nke nhazi ya na ngwaahịa.HydroxypropylMethylCellulose na-enyere aka melite nkwụsi ike nke resin ma na-achịkwa nkesa nha nha..PVC resin mere si elu àgwà HydroxypropylMethylCellulose ọ bụghị naanị nwere ike hụ na arụmọrụ akara na mba ụkpụrụ, ma nwekwara ike na-ezi pụtara nkịtị Njirimara, magburu onwe urughuru Njirimara na magburu onwe agbaze rheological omume.
Na mmepụta nke resins sịntetik, dị ka polyvinyl chloride, polyvinylidene chloride, na ndị ọzọ copolymers, nkwusioru polymerization bụ nke a na-ejikarị eme ihe na ọ ghaghị ịbụ monomers hydrophobic na-adịghị agbanwe agbanwe kwụsịtụrụ na mmiri.Dị ka polymers soluble mmiri, ngwaahịa HydroxypropylMethylCellulose nwere ọmarịcha ọrụ elu yana ọrụ dị ka ihe nchebe colloidal.HydroxypropylMethylCellulosecan na-egbochi nke ọma irighiri ihe polymeric imepụta na agglomeration.Ọzọkwa, ọ bụ ezie na HydroxypropylMethylCelluloseis a mmiri soluble polima, ọ nwere ike ịbụ ubé soluble na hydrophobic monomers na ike dịkwuo monomer porosity maka mmepụta nke polymeric ahụ.
