摘要：
The components of the rubbers tested were poly(butylene adipate), 4,4 prime -diphenylmethane diisocyanate, and a low-molecular diol. Increasing the number of methylene groups in the diol reduces the concentration of effective chains in the polymers, and hence diols of the oxyethylene series confer inferior mechanical properties to those conferred by methylene-series diols.
