摘要

利用热重分析(TGA)、红外光谱(FT-IR)和紫外可见光谱(UV-VIS)分析了顺式1,4-聚异戊二烯(天然和合成)与C60的反应性。在190℃的氮气C60下富勒烯产生交联顺式1,4-聚异戊二烯。所提出的结果结构是一个三维网络，其中C60代表结，橡胶链碎片连接结的细丝。

ON THE REACTIVITY OF C60 FULLERENE WITH DIENE RUBBER MACRORADICALS. II. THE REACTIVITY WITH CIS-1,4-POLYISOPRENE UNDER MILDER THERMAL CONDITIONS

Evidences about the reactivity of cis-1,4-polyisoprene (natural and synthetic origin) with C60 are presented by TGA data and by FT-IR and UV-VIS spectroscopy. At 190°C under nitrogen C60 fullerene causes the crosslinking cis-1,4-polyisoprene. The proposed resulting structure is a three-dimensional network where C60 represents the knots and the rubber chain fragments the filaments connecting the knots.
