Class Information
Number: 526/903
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Monomer polymerized in presence of transition metal containing catalyst and hydrocarbon additive affecting polymer properties of catalyst activity
Description: Processes of polymerizing an ethylenically unsaturated monomer in the presence of a catalyst containing a transition metal atom, and in the presence of a hydrocarbon additive, which additive affects the final properties of the produced polymer or which affects the activity of the catalyst.
