METHOD OF OBTAINING MODIFIED FILMS BASED ON POLYVINYL ALCOHOL

摘要

FIELD: chemistry. ^ SUBSTANCE: invention concerns improvement technology for films based on polyvinyl alcohol with enhanced fire and heat resistance, and can be applied in various fields of industry, science, technology and agriculture. Method involves polyvinyl alcohol films processing by mix of 5-10% aqueous solution of methylphosphate borate and 5-10% aqueous solution of chitosan at the weight ratio of 1:1, and drying. ^ EFFECT: obtainment of non-toxic biologically degradable and environmentally safe films with enhanced fire and heat resistance. ^ 1 tbl, 3 ex
