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.======以下答案可供参考======供参考答案1:From the table, each element in A copolymer 5%or measured with the theoretical approaches. B and C of copolymer S element 5%or gap with the theoretical values. This is because each polymer monomer participation in accordance with item is not certain quality than 1 to alternate. Especially the more active styrene copolymer C, styrene participation of high quality reaction.Three kinds of polymer molecular weight and the number of molecular weight were characterized by GPC. Glass transition temperature were characterized by DSC, from the table shows three kinds of glass transition temperature of the polymer resin with common glass transition temperature is close.供参考答案2:May know from the table, in copolymer A various elements percentage actual value and the theoretical value are close.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 in turn the copolymerization.In the copolymer C styrene activeness is specially high, the styrene participation response material quantity quite is high.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.供参考答案3:Can see from the table, copolymer A percentage of each element content of the measured values and theoretical values are close. Copolymer B and C, S elemental percentages of the measured value and the substantial gap between the theoretical value. This is due to the participation of reactive monomer is not necessarily carried out in accordance with alternating copolymerization mass ratio of 1:1:1. Particularly in the styrene copolymer C activity was higher in the mass ratio of styrene in reaction high.
