碩士 === 國立成功大學 === 化學工程研究所 === 83 === In this research ,monomer containing siloxane on side chains was prepared and copolymerized with acrylic acid or acrylic am- ine and steryl acrylate . The copolymers were used for improvi- ng the antiwear effect and modifing the viscosity index . The viscosity index of lubricating oil was calculated accor- ding to ASTM-2270 , and it was improved by adding the prepared copolymers that were prepared. TheSEM photographs showed that copolymers containing-N(CH3)2 groups or -COOH group performed a thick oil film on the worn surface of rollers and it is thicker for the former than for the latter . The ESCA photoelectronspetra gave the evidence that the cop- olymers had been already adsorbed on the roller surface by means of analyzing the elements of Fe , C , O , N , Si on the metal surfaces
