Question

英语翻译从表中可知,共聚物A中各元素百分含量实测值与理论值较为接近.共聚物B和C 中 S 元素百分含量实测值与理论值存在

Answer 1

May know from the table,in copolymer The various elements percentage actual value and the theoretical value are closer.In copolymer B and C S element percentage actual value and theoretical value existence big disparity.This is because various polymers monomer participation response not necessarily is defers to the material quantity to compare 1:1:1 carries on alternately the copolymerization.In the copolymer C styrene activeness is specially high,the styrene participation response's material quantity is quite high.the three kind of polymer number even molecular weight and the heavy even molecular weight use GPC to carry on the attribute.The vitrification transition temperature uses DSC to carry on the attribute,sees three kind of polymers from the table the vitrification transition temperatures and the common resin vitrification transition temperature approaches.
