Shrinkage-resistant polymers

摘要

The present invention provides moisture curable polyacrylate compositions, which cured elastomers thereof demonstrate improved resistance to shrinkage when exposed to hydrocarbon fluids such as transmission fluids and oil and fuel based fluids. Such compositions include: a) a moisture curable silyl functionalized polyacrylate; and b) at least one hydrocarbon fluid-absorbing component, wherein the hydrocarbon-fluid absorbing component is present in an amount sufficient to reduce shrinkage of the cured composition when exposed to a hydrocarbon fluid.
