双苯螺磷阻燃剂的合成及应用

本文介绍在采用苯基二氯磷酸酯与季戊四醇反应合成双苯螺磷阻燃剂时，不用催化剂、不用反应溶剂、不用缚酸剂及用不同的精制方法进行了试验，可以较简便较高收率制得产物双苯螺磷阻燃剂，将其6～8份Phr添加于ABS树脂，可得到UL94V-2（3．2mm）级阻燃效果，并且无泛黄变色问题，还有较好熔体流动性等优异特点。     

The Bisphosphonate Clodronate Modifying Hydroxyapatite Bioceramics for Bone Scaffold

To investigate the efficiency of clodronate modifying HA bioceramics,and to evaluate the effect of clodronate modifying HA bioceramics on the cells in vitro,clodronate modified the porous HA bioceramics for bone scaffold by chelation .The outermost layer of the specimens was analyzd by XPS and FI-IR ,The depth profile was investigated by the argon-ion sputtering method.The cell culture test was conducted using MC3T3-E1 osteoblastic cells,The cells were inoculated and cultured on the scaffolds.Morphological observation of the cells,MTT test and ALP activity test evaluated the cell attachment ,proliferation and activity on the scaffolds.The cell culture test in cell quantity and morphology indicated active proliferation of the cells on the scaffolds.The ALP activity of the cells cultured for 3d and 7d on clodronate-HA bioceramics was slightly higher than that on HA bioceramics ,but the difference was not signifcant,This result indicated that clodronate-HA bioeramics had favorable cytocompatibility to be used as bone scaffold with potential ability to improve asteogensis.
