Nkọwa ngwaahịa
Homopolymer polypropylene bụ polymer kpụrụ site na polymerization nke propylene monomer naanị.Homopolymer polypropylene bụ ọkara kristal polymer.N'ihi nnukwu crystallinity ya, polypropylene homopolymer nwere ezigbo ihe eji arụ ọrụ.Gụnyere nnukwu ihe siri ike, ike dị elu, ezigbo nkwụsị ọkụ na nrụrụ.N'otu oge ahụ, n'ihi na nke ọma fluidity, elu crystallization okpomọkụ shortens na ịkpụzi okirikiri nke ngwaahịa.A na-eji homopolymer polypropylene eme ihe n'ọtụtụ ebe na ntụtụ, eserese na nhazi na nhazi usoro ndị ọzọ.
