中文摘要:
      研究橡胶树割胶后不同采集时段天然橡胶(NR)的相对分子质量及其分布、热稳定性、交联密度,提出高品质大相对分子质量NR的采集方法。结果表明,橡胶树割胶后采集时段为30~45 min NR的相对分子质量大、相对分子质量分布窄、热稳定性好、交联密度大,商业采集高品质大相对分子质量NR应集中在这个时段。
英文摘要:
      Study on the molecular weight and its distribution,thermal stability and cross-linking density of natural rubber(NR) at different collection periods after Haeve brasiliensis tapping.The collection method of high-quality and large molecular weight NR was proposed.The results showed that the NR during the collection period of 30~45 min after tapping had a large molecular weight,narrow molecular weight distribution,good thermal stability and high cross-linking density.Therefore a commercial collection of high-quality NR with large molecular weight should be concentrated in this period.
