                    Abstract: The research on the flame retardancy and flame retardant mechanism of polyphenyl
                phosphate resorcinol ester (PRPP) as a substitute for RDP in flame retardant PC/ABS has not been reported in
                the literature, which is in line with the development direction of current flame retardant technology, and has
                important theoretical significance and practical value. The PRPP was used for the flame retardant of PC/ABS,
                and the samples with different ratios were tested for oxygen index, vertical burning, and thermal properties.
                The optimum ratio is obtained by analysis. Finally, the flame retardant modification of RDP and PRPP to PC/
                ABS were compared. The results show that as a solid flame retardant, PRPP has similar flame retardant effect
                with liquid flame retardant RDP and BDP which have same structure with PRPP. The oxygen index of the
                modified material is improved compared with the unmodified material. It has the unparalleled advantages
                of liquid flame retardant in processing, transportation and storage. It can be used as a substitute for RDP and
                BDP flame retardants in the range of conventional use.

                properties

                         朗盛计划向沙特阿美出售合资公司阿朗新科剩余 50% 股份

                    朗盛计划将自身持有的 50% 阿朗新科股份出售给合资伙伴沙特阿美。两家公司曾于 2016 年以各自出资 50%
                的形式成立合成橡胶企业阿朗新科,今日已分别签署交易协议。
                    此项交易还需接受相关反垄断部门的审批。此外,两家公司将与相关员工代表和工会进行商议会谈,预计于
                2018 年年底正式完成交易。
                    合资企业阿朗新科的总市值为 30 亿欧元。扣除与自身所持 50% 股份相关的借款及其他金融负债后,朗盛预
                计将在此项交易中获得约 14 亿欧元现金。
                    朗盛计划用该笔收入巩固自身财务基础,削减净负债。
                    最初,朗盛与沙特阿美达成了合作锁定期至 2021 年的协议。朗盛管理董事会主席常牧天表示 : “ 这笔计划中
                的交易标志着我们将提前达成战略转型之路上的又一座重要里程碑,它将使我们更为专注地巩固在中等规模特殊
                化学品市场上的领先地位。与此同时,我们也将提升自身业务的适应力,夯实财务基础,并确保更大的战略灵活性,
                为未来增长做好准备。”

                    总部位于荷兰马斯特里赫特的阿朗新科在 9 个国家设有 20 座生产基地,旗下约有 3  800 名员工,2017 年的
                销售额约为 32 亿欧元。该公司主要生产用于汽车轮胎、建筑与石油天然气等行业的高性能橡胶。
                    2016 年,通过将合成橡胶业务并入合资企业阿朗新科,朗盛为自身的战略调整计划奠定了基础。此后,朗
                盛致力于开发中等规模特殊化学品市场,并在该领域完成了多笔收购 —— 其中规模最大的交易为 2017 年对美国
                科聚亚化学公司的收购。
