-NCO基硅氧烷底涂剂对聚氨酯密封胶粘接性能的影响

采用有机溶剂稀释KSA(-NCO基硅氧烷化合物),并以此作为单组分湿固化聚氨酯(PU)密封胶的玻璃基材底涂剂。采用单因素试验法考察了无底涂剂试样、含传统Z-6040底涂剂试样和含KSA底涂剂试样对PU密封胶与玻璃基材之间粘接性能的影响。结果表明:当KSA底涂剂的固含量为15%、底涂剂与密封胶的涂敷间隔时间为15 min时,含KSA底涂剂的试样比含传统Z-6040底涂剂的试样更能有效提高PU密封胶与玻璃胶接件的综合性能;前者的剥离强度为9.5 N/mm且为内聚破坏,水中浸泡7 d后其剥离强度仅下降32%,4次高低温循环后其剥离强度仍高达4.1 N/mm。

Different surface‐substituted polyorganosiloxane microgels as support materials for MAO‐type cocatalysts

Twenty‐five different functionalized and nonfunctionalized polyorganosiloxane microgels were applied as support materials for methylalumoxane (MAO)‐type compounds to give various heterogeneous cocatalysts which are able to activate metallocene complexes like Cp₂ZrCl₂ for ethene polymerization. The functionalization of the microgels has a strong influence on the properties of the catalysts and the produced polyethenes. © 2001 John Wiley & Sons, Inc. J Appl Polym Sci 80: 281–285, 2001     

Acrylic terpolymer modified by blending with polyorganosiloxane polymer or reinforcing

Blending of acrylic terpolymer (AT) and polyorganosiloxane (PSP) resulted in homogeneous blends with improved mechanical properties and better outdoor weathering resistance. Similarly, incorporation of glass fibres in concentrations of 1–3% produced substantially better mechanical properties and enhanced outdoor durability in the resulting blends.     

The study of complex mineral silicates by trimethylsilylation

The Lentz trimethylsilylation technique has been applied to study four micas: biotite, phlogopite, muscovite and suzorite. The Lentz derivitisation technique is shown to be independent of the exact amount of phase transfer agent (propan-2-ol or ethanol) present in the trimethylsilylation of the micas as long as the ratio of mineral to hexamethyldisiloxane is held constant. The polyorganosiloxane product distribution is shown to be largely dependent on the amount and distribution of Al³⁺ present in the tetrahedral layers of the micas.
