ABSTRACT:
A novel cyclopentadiene derivative of the general formula: ##STR1## wherein R.sup.1 is hydrogen, a mono- to tetra-hydric alcohol moiety having 1 to 12 carbon atoms, a metal of Groups Ia, IIa and IIb of the Periodic Table, an ammonium group or an organic amine residue; R.sup.2, R.sup.3, and R.sup.4 are independently hydrogen or alkyl groups having 1 to 6 carbon atoms; R.sup.a, R.sup.b, and R.sup.c are independently hydrogen or alkyl groups having 1 to 3 carbon atoms; m is 0 or 1; and n is an integer of 1 to 4. This cyclopentadiene derivative is comparable or even superior to natural rosin in effectiveness as an emulsifier for use in the production of SBR and ABS resins or as a sizing agent in paper making.
