Abstract
FIELD: chemical technology. SUBSTANCE: method involves addition of chemically inert to radiation additions to polypropylene. Article is made and irradiated at increased temperatures - by 5-40 C lower of polypropylene melting point. Also, stabilizing agents, filling agents, dyes, elastomers and other special additions can be added to polypropylene. Method ensures to improve hardiness, stability to ageing, heat stability and other properties at increased temperatures (below 220 C). EFFECT: improved method of producing, quality and property.
