摘要：
New paraphenylene diamine antioxidants were prepared. The efficiency and permanence of these oligomer-bound paraphenylene diamines were compared with those of conventional amine-type antioxidants in elastomer blends such as natural rubber/ styrene- butadiene rubber and natural rubber /polybutadiene rubber. These oligomer-bound antioxidants showed improved aging resistance and ozone resistance in comparison with the blends containing conventional antioxidants. The liquid oligomer-bound paraphenylene diamine could replace the plasticizer required for compounding. (C) 2004 Wiley Periodicals, Inc.
