摘要：
The copolymerization behavior of ethylene and 1-butene in a slurry reactor was investigated using chromium-silica catalyst at 0-50 °C. Different ethylene to 1-butene feed ratios were used, copolymerization rate and yields increased with the addition of 1-butene to ethylene. Diffusion limitation was influenced by the copolymerization rates of the polymers at temperature above 30 °C.
