TL;DR: In this article, the authors provided compositions that consisted of a polymer selected from the group consisting of an ethylene/α-olefin multiblock interpolymer; a propylene based plastomer or elastomer; and a mixture of (a) and (b) filler based on the weight of the composition; and (c) an effective amount of tackifier.
Abstract: Compositions are provided that comprise: (1) a polymer selected from the group consisting of: (A) an ethylene/α-olefin multiblock interpolymer; (B) a propylene based plastomer or elastomer; and (C) a mixture of (A) and (B); (2) from about 1 to about 75 weight percent filler based on the weight of the composition; and (3) an effective amount of tackifier.

TL;DR: In this article, a polyolefin-based heat sealable and peelable seal having improved haze values was proposed, which consisted of from about 45 to about 55 percent by weight of a propylene-based plastomer or elastomer and.
Abstract: The invention relates to a polyolefin-based heat sealable and peelable seal having improved haze values. The peelable seals comprise from about 45 to about 55 percent by weight of a propylene based plastomer or elastomer and.from about 45 to about 55 percent by weight of low density polyethylene. Such peelable seals exhibit total haze values of less than about 8 percent, based on a film thickness of 50 microns.

TL;DR: A review of thermoplastic elastomers (TPE) combining the properties of chemically cured rubbers with facility of processing and recycling of thermopolymers is presented in this article.
Abstract: A review (81 references mainly from the period 2000-2003) concerning new thermoplastic elastomers (TPE) combining, in the defined temperature range, the properties of chemically cured rubbers with facility of processing and recycling of thermoplastic polymers Four groups of such products were singled out, namely: block copolymers of styrene (mainly with butadiene, isoprene or isobutene; in a last case also graft copolymers), elastomeric polyolefins (based on propylene), thermoplastic elastomers made of polymer blends (physical blends of crystallizing plastomer with not crosslinked elastomer) and thermoplastic elastoionomers (elastomers containing side ionogenic acid groups, most often carboxylic or sulfonic ones) The principles of syntheses of TPE were discussed and directions of their applications as well as the present state and perspectives of their industrial manufacturing were presented

TL;DR: In this article, a wide die gap was used so that a fracture-free polyolefin plastomer film could be obtained with no PPA present for comparison purposes, and the films were analyzed for the following properties: surface tension (on treated films), gloss, haze, clarity, transmittance, hot tack, heat seal, COF and block.
Abstract: Polyolefin plastomer films formulated with slip and antiblock were blown on a wide die gap with and without two DynamarTM polymer processing additives (PPAs). A wide die gap was used so that melt fracture-free film could be obtained with no PPA present for comparison purposes. The films were analyzed for the following properties: surface tension (on treated films), gloss, haze, clarity, transmittance, hot tack, heat seal, COF and block. In addition, the surface of films was examined using ESCA (Electron Spectroscopy for Chemical Analysis) and SSIMS (Static Secondary Ion Mass Spectrometry) to determine the surface chemical composition. PPAs when used at typical dose levels were shown to have essentially no effect on the surface and optical properties of plastomer films.
