Reactive carbonate for elastomeric articles

Abstract

This disclosure describes the preparation and use of reactive carbonates containing a metal carbonate bound to a reactive compound, wherein the reactive compound comprises a mineral binding group anda polymer reactive group connected together by a linking group. Such reactive carbonates are useful as reagents in processes for making mineral-bound elastomeric materials, and in methods for reducingcavitation in elastomer materials.

Description

[0001] priority claim [0002] This PCT International Application claims the benefit of priority to U.S. Provisional Application No. 62 / 571,035, filed October 11, 2017, the subject matter of which is incorporated herein by reference in its entirety. technical field [0003] The present application relates generally to materials technology, and more specifically to the preparation and use of reactive carbonates capable of imparting certain properties to polymeric materials. The present application discloses a method of preparing a mineral-bound elastomeric material in which a metal carbonate is bound to a polymer matrix via a polymer matrix unit comprising a mineral-binding group and a linking group. The reactive carbonates disclosed herein may also contain a metal carbonate bonded to a reactive compound comprising mineral binding groups, polymer reactive groups, and linking groups. Such reactive carbonates can be used, for example, in methods of reducing cavitation in elastom...
