Abstract
A polymeric compound involves a blend of 50 wt % or greater of a thermoplastic having an average melting point (Tm) of less than 200 ° C. and less than 50 wt % of a butyl rubber ionomer dispersed in a matrix of the thermoplastic, weights based on total weight of the thermoplastic and butyl rubber ionomer. Such blends may exhibit improved physical properties compared to unblended thermoplastic, particularly ultimate elongation and/or damping. The polymeric compounds are useful for forming a variety of articles of manufacture.
