摘要:
The invention relates to functionalized interpolymers derived from base olefin interpolymers, which are prepared by polymerizing one or more monomers or mixtures of monomers, such as ethylene and one or more comonomers, to form an interpolymer products having unique physical properties. The functionalized olefin interpolymers contain two or more differing regions or segments (blocks), resulting in unique processing and physical properties.
摘要:
A thermoplastic composition is described that comprises (i) from 1 to 99 percent by weight of the total composition of at least one thermoplastic copolymer, for example, styrene block copolymers, and (ii) from 1 to 99 percent by weight of the total composition of at least one homogeneously branched ethylene/α-olefin interpolymer, for example ethylene/1-octene, having a density of less than or equal to 0.899 g/cc and a Brookfield viscosity of greater than 500 cP (350° F.).
摘要:
A filled thermoplastic olefin composition comprising (a) a first polypropylene having (i) substantially isotactic propylene sequences, (ii) a narrow molecular weight distribution, and (iii) a broad composition distribution, and (b) at least about 20 percent by volume filler based on the total volume of the composition. Optionally, the composition can comprise a second polypropylene different for the first polypropylene, both polypropylenes preferably propylene/α-olefin copolymers. The filler can be organic or inorganic, and the compositions are useful as, among other applications, protective coverings for wire and cable.
摘要:
A novel flooring composition was developed based on a blend comprising: a) an elastomer; b) a random propylene/alpha-olefin copolymer; c) a cross linking agent; and optionally d) a melt strength enhancing polymer. This composition achieves a unique balance of properties, exhibiting often-conflicting performance requirements. These include low gloss and excellent pattern duplication in embossing, low modulus, minimal odor, excellent grain acceptance and abrasion resistance, while remaining thermoformable and maintaining minimal shift in viscosity during recycle.
