Abstract
There are disclosed a gel or polymer composition which comprises 100 parts by weight of a polymer blend component comprising 1 to 90% by weight of a poly(vinyl aromatic hydrocarbon) polymer having a syndiotactic configuration and 99 to 10% by weight of a rubbery elastomer and at least 30 parts by weight of an extender oil or a low molecular weight organic component. These gel compositions have super soft properties, heat resistance, and/or damping properties.
