[ 1 ] - بررسی اثر آنتی اکسیدان بر فرایند کهولت اکسایشی رزین پلی بوتادی - ان با گروه هیدروکسیل انتهایی

Hydroxyl terminated polybutadien that is known as HTPB resin is a liquid hydrocarbon polyol that is commonly used in preparation of solid composite propellants. Because of unsaturated nature of repeating unit of HTPB polymer , it has high potential for oxidative aging . In this paper ,we have investigated aging behaviors of two types of HTPB which having various content of phenolic antioxida...
