Poly bd® R20 LM resin is a low molecular weight, liquid hydroxyl terminated polymer of butadiene. 

Poly bd R45 M resin is a liquid hydroxyl terminated polymer of butadiene. Poly bd resins have primary, predominantly allylic hydroxy groups that exhibit high reactivity in chemical reactions for the preparation of derivatives.

Poly bd® R45 HTLO resin is a low molecular weight, liquid hydroxyl terminated polymer of butadiene.
