dc.description.abstract |
In this study silanized hydrogenated palm stearin was synthesized by reacting hydrogenated palm stearin with vinyltrimethoxysilane via free radical reaction. Dicumyl peroxide was used as initiator. The characterization of silanized-HPS was done by 1H NMR and FT-IR spectroscopy. Homopolymer of silanized-HPS was synthesized by moisture curing. The silanized-HPS homopolymer was characterized by IR spectroscopy. The effect of the crosslink density upon moisture cure on the mechanical properties, thermal properties and swelling of silanized-HPS polymer was analyzed by surface hardness test, DSC (Differential Scanning Calorimetry), swelling test respectively. According to swelling test and surface hardness tests, silanized-HPS shows heterogeneous distribution of crosslinks in crosslinked areas. Hydrophobicity of silanized-HPS coated glass surface was studied by water contact angle measurements and the contact angles reach their maximum value of 107°. |
