An insulation useful in the field of building materials, refrigeration, cryogenics, and shipping. The insulation has reduced radiative heat transfer by applying coating to the insulation material in order to alter the emissivity, including the infrared electromagnetic spectrum.

Described herein are poly(arylene sulfide) (“PAS”) polymers (PASP) including recurring units formed from selected dihalofluorene monomers. Surprisingly, at relative low dihalofluorene monomer concentrations, the PAS polymers (PASP) have significantly increased glass transition temperatures (“T.sub.g”) and impact performance, relative to analogous PAS homopolymers and PAS polymers (PASP) including recurring units formed from 4,4′-dibromobiphenyl (“DBBP”). Simultaneously, the PAS polymers (PASP) also retain high elastic modulus. Furthermore, the PAS polymers (PASP) are free of recurring units formed from polyhalogenated biphenyls (e.g. DBBP and polychlorinated biphenyls) and, therefore, are not currently subject to restrictive governmental regulation. Due at least in part to the excellent thermal (T.sub.g, T.sub.c and T.sub.m) and impact properties of the PAS polymers (PASP), the PAS polymers (PASP) and PAS polymer compositions can be desirably incorporated into wide variety of articles including, but not limited to, automotive articles, electrical and electronic articles, articles for aerospace and oil and gas articles.
