The invention relates to an one pack ambient cure crosslinkable modified vinyl branched ester polymer with vinyl silane and a water scavanger. The copolymer composition can be formulated to the desired viscosity that allows the application by standard technics, and the curing is optimized in the presence of an appropriated catalyst as one pack system to be cure at room temperature.

Articles made from a moisture-curable, polymeric composition comprising in weight percent based on the weight of the composition: (A) 2 to less than 80 weight percent (wt %) of an ethylenic polymer with (1) a crystallinity at room temperature of 34% to 55%, or 65% to 80%, and (2) a melt index (I.sub.2) of 0.1 to 50 decigrams per minute (dg/min); (B) 3 to 30 wt % of a halogenated flame retardant; (C) 3 to 30 wt % an inorganic antimony flame retardant; and (D) 0 to 10 wt % of at least one of an inorganic flame retardant other than the inorganic antimony flame retardant, e.g., zinc oxide
exhibit enhanced ACBD properties in comparison to articles alike in all respects except made from a composition comprising an ethylenic polymer without the requisite crystallinity at room temperature.

An external additive particle includes a sulfur-containing polymer. The polymer includes a vinyl polymer moiety and a siloxane moiety. The proportion of the number of silicon atoms to the sum of the number of carbon atoms, the number of oxygen atoms, and the number of silicon atoms in the external additive particle is 4.0% or more and 25.0% or less, and sulfur atoms are contained in the surface of the external additive particle as detected by X-ray photoelectron spectroscopy.

The present invention relates to a powder slush molded body of a polyvinyl chloride composition, the polyvinyl chloride composition containing a polyvinyl chloride, a plasticizer, and an acrylic polymer. The polyvinyl chloride composition contains the plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less with respect to 100 parts by mass of the polyvinyl chloride. When a cross section of the powder slush molded body extending in parallel with a thickness direction is observed under an optical microscope using reflected light, irregular scale-like polyvinyl chloride particles having a long diameter of 30 μm or more and 500 μm or less are continuous with one another via interfacial portions, and the number of aggregated particles of the acrylic polymer having a long diameter of 30 μm or more and 100 μm or less is 10 particles/mm.sup.2 or less. Thus, provided are a powder slush molded body of a polyvinyl chloride composition having high flexibility after heat aging as well as favorable surface characteristics, and a laminate.
