摘要：2-甲基-2-丙烯酸-2[(2,3,3A,4,7,7A-六氢-4,7-亚甲基-1 氢-茚基)氧]乙酯（DCPEMA）与双环戊二烯（DCPD）
经开环易位聚合反应制备了共聚物，对聚合工艺进行了考察，采用 FTIR 对其结构进行了表征，探讨了 n(DCPD)∶
n(DCPEMA)对共聚物表面亲水性、力学性能及玻璃化转变温度（T g ）的影响。结果表明，DCPEMA 通过打开烯
烃双键的方式与 DCPD 生成共聚物。随着 DCPEMA 用量的增加，共聚物的静态水接触角、拉伸强度和 T g 逐渐
降低，断裂伸长率和溶胀率呈先升高后下降的趋势。共聚物的静态水接触角、拉伸强度由聚双环戊二烯的 110°
和(64.5±2.3) MPa 下降至 43°和(9.1±1.5) MPa。当 n(DCPD)∶n(DCPEMA) = 2∶1 时，共聚物的断裂伸长率达到
最大，为 68%±2%，拉伸强度为(14.1±3.4) MPa。

Abstract: A copolymer of 2-propenoic acid, 2-methyl-2-[(2,3,3A,4,7,7A-hexahydro-4,7-methano-1H-indenyl)oxy]
ethyl ester (DCPEMA) with dicyclopentadiene (DCPD) was prepared by ring-opening translocation
polymerization. The polymerization process was investigated. The structure was characterized by FTIR.
The effects of molar ratio of DCPD to DCPEMA on hydrophilicity, mechanical properties and glass
transition temperature (T g) of copolymer were investigated. The results showed that DCPEMA formed
copolymer with DCPD by opening the olefin double bond. With the increase of dosage of DCPEMA, the
static water contact angle, tensile strength and T g of copolymer decreased gradually, and the breaking
elongation and swelling ratio increased first and then decreased. The static water contact angle and tensile
strength of the copolymer decreased from 110° and (64.5±2.3) MPa to 43° and (9.1±1.5) MPa. The
maximum breaking elongation and tensile strength of the copolymer with n(DCPD)∶n(DCPEMA) = 2∶1
were 68%±2% and (14.1±3.4) MPa, respectively.
