ABSTRACT:
Organic prepolymer fillers capable of curing and reacting chemically with elastomers to form covalent bonds therewith are mixed with elastomers to form reinforcing domains with diameters of from 0.01 to about 50 microns, and when the mixture is cured, the mechanical strength of the elastomer is increased. In many cases, the thermal stability and/or the hydrolytic stability will also be increased.
