This paper deals with a proposal to the young polymer scientist from the old through the accidental discovery of the catalyst which gives low crystalline syndiotactic 1,2-polybutadiene. The key point of the discovery were the molar ratio of aluminum compound /water, and the structure of the ligands.
Although the discovery was serendipitous, it would not have happened if careful observation and operation hypothesis were not made during the research.
