TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - The mineral filler comprises at least one halogen free filler. The mineral filler used in the article comprising the roofing material, is selected from magnesium dihydroxide, aluminum trihydroxide and/or antimony trioxide, preferably magnesium dihydroxide; and in the article comprising sound deadening material is selected from talc, carbon black, graphite, calcium carbonate, flyash, cement dust, clay, feldspar, nepheline, silica or glass, fumed silica, alumina, magnesium oxide, zinc oxide, barium sulfate, aluminum silicate, calcium silicate, titanium dioxide, titanate, glass microsphere and/or chalk.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The composition comprises (wt.%): propylene copolymer (greater than or equal to 5, preferably greater than or equal to 50) and rubber component (10 - 40). The composition has a Shore A Hardness of greater than or equal to 90; and a tensile strength of at least 9 MPa, as measured according to ISO 37-1, Type S2. Preferred Components: The propylene copolymer is a propylene/ethylene copolymer having an ethylene content of 5 - 30 wt.%. The polyolefinic thermoplastic resin component comprises polypropylene homopolymer, isotactic polypropylene, an impact copolymer comprising polypropylene, or their blend; or polypropylene having a heat of fusion greater that 45 J/g in an amount of 5 - 10 wt.%, based on total weight of the vulcanizate composition. The dispersed rubber component is at least partially vulcanized; and includes at least one thermoset rubber. EXAMPLE - A composition (test) comprising (wt.%): KWDA 372 (30.75), HiFax CA10A (RTM; thermoplastic olefin polymer) (23), Magnifin H5GV (RTM; magnesium hydroxide) (40), TiO2 (2.75), PP4045 (carbon black master batch in polypropylene resin) (0.10), Tinuvin 327 (RTM; UV absorber) (0.40), Irganox 1010 (RTM; antioxidant) (0.20), Fusabond 353D (RTM; chemically modified polypropylene) (2), Irganox PS800FL (RTM; antioxidant) (0.30) and Tinuvin 770 DF (RTM; hindered amine) (0.50) was prepared. A comparative (control) composition was prepared in similar manner by using S201-64 (RTM; thermoplastic vulcanizate) instead of KWDA 372. Both test/control compositions were tested for their properties. The results of test/control composition for shore A hardness; shore B hardness; elongation, tensile, tear strength and 100% modulus were found to be 92/93; 33/34; 527/456; 10.5/9.4 and 42/42 respectively.
