Scheer stresses that his team's main goal is to derive a monomer—the building block of the polymers most of us call plastics—entirely from algae biomass.
舍尔强调他们的主要目标在于研发一种单体物质-我们大多数人称为塑料的一种聚合物的构件---完全来源于海藻这种生物质原料。
These catalyst systems are generally used to produce polyolefins having broad molecular weight distributions, especially polyethylene. Some systems are used to produce branched or block polymers.
大多数含茂金属的双组分或多组分催化体系用于制备宽分子量分布聚烯烃，尤其是宽分布聚乙烯，少数用于制备支化或嵌段聚合物。
