    Abstract: A process for the production of lower molecular weight polymers by free radical polymerization, characterized in that there is added to the polymerization system a compound of the general formula I ##STR1## wherein R.sup.1 is hydrogen, chlorine, an alkyl group, or a group capable of activating the vinylic carbon towards free radical addition; R.sup.2 is hydrogen or an optionally substituted alkyl, alkenyl, aryl, cycloalkenyl or cycloalkyl group or the group --COZ, where Z is R.sup.3 or OR.sup.3, where R.sup.3 is hydrogen or an optionally substituted alkyl, alkenyl or aryl group. X is a hydrogen atom, an alkyl or aryl group, or a halogen, and the two X groups may be the same or different. The invention also includes polymers or oligomers made by the process and novel compounds of the general formula I as defined above.

    Abstract: A process for the suspension agglomeration of amidoperoxyacids which leads to improved rheological storage stability of aqueous suspensions made from these agglomerated peroxyacids is disclosed. Also disclosed are aqueous suspensions of stable viscosity made by milling these agglomerates to a mean particle size of about 20 to about 75 microns.
