摘要
采用乳液聚合法原位合成以无机物SiO2为核、苯乙烯-丙烯酰胺共聚物(PSAm)为有机/无机壳的核壳粒子,并负载Fe(Ⅱ)后过渡金属催化剂,并考察了PSAm/SiO2核壳载体制备过程中搅拌速率、乳化剂用量等对反应的影响,采用扫描电镜(SEM)、偏关显微镜(PLM)、红外光谱(FTIR)等分析方法对PSAm/SiO2核壳载体进行了表征.
Late-transition metal catalyst Fe （ Ⅱ ） was supported on core-shell particle synthesized in-situ by emulsion polymerization, where SiO2 served as core and PSAm served as shell. The influence of stirring speed, initiator and emulsifier on the performance of core-shell particle is studied. The obtained support was characterized by FTIR, SEM, and PLM etc.
