抄録

Synthetic cis-1, 4 polyisoprene (IR) was esterified with Stearic acid selectively at 3, 4 units by hydroboration with 9-borabicycro[3.3.1]nonane (9-BBN) followed by esterification with stearoyl chloride. The hydroxylation suppressed the crystallization of IR. The esterification of hydroxylated IR with 0.53wt% stearoyl group resulted in an increase in the rate of crystallization at -25°C, but not with 0.34wt% stearoyl group. A similar stimulation effect was observed by mixing stearic acid of 0.53wt%. The effect of mixed stearic acid on the rate of crystallization of IR was dependent on the amount of mixed or linked stearic acid.
