Wathen G. D., . and Gent A. N., . Slow crystallisation of natural rubber latex. pp. 178-181. ISSN 0127-7065
Abstract
Samples of natural rubber latex (with ethyiene glycol added to prevent freezing) did not crystallise to a measurable extent on standing for one week at - 29C. In contrast coagulated latex rubber has a half-life of crystallisation of only about 2 hat this temperature and purified solid rubber has a half-life of only about 8 h. It is concluded that latex rubber particles about 0.5 um in diameter crystallise more than one hundred times slower than solid rubber probably because crystal nuclei are relatively scarce in rubber with a concentration of less than one nucleus in fifty latex particles or in 106 rubber molecules.
