근래 고성능 친환경 타이어의 개발요구에 의하여 경제성(낮은 회전 저항)과 안전성(wet traction) 및 내마모성 면에서 균형있는 특성을 가지는 타이어 트레드 고무의 합성 제조 기술이 중요하게 대두된다. 이를 위하여 다양한 기능성 용액중합 SBR의 개발과 함께 고무/충전제 간의 상호작용 증진 기술이 학술적으로나 산업적으로 활용되고 있다. 본 고에서는 기존의 카본블랙 고무와 함께 최근 green tire로서 각광 받는 실리카 충전 고무에서 충전제와 상호반응이 가능한 화학적 변성 SBR과 커플링제를 이용한 고성능 타이어 트레드 고무의 합성 제조 기술에 대하여 최근 연구 방향과 함께 작용 메카니즘에 대하여 고찰하였다. The specialized and diversified synthetic and compounding technologies are used to meet the requirements for the advanced high performance tire tread materials with better balance of fuel economy(rolling resistance), safety(wet traction) and wear resistance. These techniques involve the methodology for the improvement of chemical and physical interaction between filler and the rubber matrix using coupling agents as well as a variety of chemically-modified solution SBRs. The research trends about the high performance functional SBRs and coupling agents which can interact with the surface of fillers and their working mechanism were investigated in the conventional carbon black-filled rubber and silica-filled SBR systems developed recently as green tire.

Research on autonomous vehicles, such as lane recognition, sign recognition, LiDAR data processing, and avoidance control, continues to expand, and recently, commercially available vehicles were partially supplied with level 3 autonomous driving technology for use in highway environments. However, in urban environments, the application of level 3 technology is limited due to variables such as traffic lights and pedestrians. For this reason, for autonomous driving in urban environments, an integrated system of technologies for responding to many variables, such as road component recognition and obstacle avoidance, is required. However, if each sensor in the integrated system malfunctions or arrives at different judgment based on the same situation, a problem in vehicle control may occur due to exclusive data collision. Therefore, this paper proposes an integrated control system that develops a technology for responding to situations that occur during driving in urban environments, such as lane recognition, traffic light recognition, and obstacle avoidance, and gives priority to each algorithm. Experiments were conducted to confirm the performance of each algorithm and to verify the performance of the integrated system. Experiments were conducted at various section of K-City(an autonomous driving test city in Korea). This integrated system showed how to appropriately respond to common situation in urban driving while considering many factors such as left turn, right turn, straight driving, and emergency braking. It is expected that the system proposed in this study and the experimental results obtained in K-City can be applied to actual urban environments in order to reflect various adverse conditions, such as road damage, encountered while driving on roads.
양이온 개환 중합을 이용한 Ethylene oxide와 Epibromohydrin의 공중합

Well-defined copolyethers derived from Ethylene oxide (EO), Epibrmohydrin (EBH) was synthesized by cationic ring-opening copolymerization. This polymerization was controlled to proceed by activated monomer (AM) mechanism in order to obtain the desired molecular weight, narrow molecular weight distribution, and copolymer composition. In this polymerization 1,4-Butandiol was used as an initiator and BF₃·OEt₂ was chosen as a cationic catalyst.
