Group IV: Polyalphaolefins (PAO's) are made by combining 2 to more decene molecules into an oligomer, a short-chain-length polymer.

聚（包）是由结合2更癸分子成低聚，短长链聚合。

Results indicate interestingly that the double bond of GMA polymerized with polystyryl carbanion and the molar ratio of epoxy end group and polystyrene oligomer can be adjusted.

GMA聚苯乙烯离子反应中，GMA活性种终端发生了聚合，所得产中环氧端基聚合产摩尔比可根据需要进行调节。
