| Abstract: | Based on the comments upon the technological problems of commercialized SBS or SIS, its molecular structure,the cost of product and the properties of the end product,the compo- sition of a new type of thermoplastic elastomer SISIS has been designed firstly; thereafter, the above-mentioned pentablock copolymer was synthesized by using modified naphthalene lithi- um as initiator, cyclohexane as solvent and through three-stage addition of styrene, isoprene, styrene monomers, respectively; at last,the end product was verified on the experimental re- sults obtained by means of GPC,IR and 'H-NMR measurements. |
