Sealant compositions having, as an essential component, hydrogenated polybutadiene as network polymer

摘要

A conventional sealant composition having as its essential rubber components (1) at least one high molecular weight, hydrogenated polybutadiene polymer, and (2) at least one low molecular weight liquid elastomer, i.e., polybutene, as tackifying polymer, compatible to a high degree with said hydrogenated polymer; the resultant sealant composition reflecting a co-continuous phase morphology wherein said hydrogenated polymer provides a crosslinked network in said compatible low molecular weight liquid elastomer.
