TL;DR: In this paper, a polypropylene sheet having a peeling layer that is well-suited to bond detachably to coated or uncoated fibrous substrates is described.
Abstract: The present invention relates to a polypropylene sheet having a peeling layer that is well-suited to bond detachably to coated or uncoated fibrous substrates. The peeling layer comprises a combination of polypropylene, preferably between 20% and 70%, and a polyolefinic plastomer having a density of 0.85 to 0.89 g/cm 3 , preferably between 30 and 80%, that meets this requirement without further additives such as bonding enhancers, inorganic fillers or polar polymers.

TL;DR: In this paper, a low permeability pipe resistant to high pressures for adducting a fluid in a motor vehicle comprising at least one layer comprising a fluorinated plastomer and an elastomeric material was proposed.
Abstract: The invention relates to a low permeability pipe resistant to high pressures for adducting a fluid in a motor vehicle comprising at least one layer comprising a fluorinated plastomer and an elastomeric material, in which the fluorinated plastomer is in a greater amount with respect to the elastomeric material. The pipe may further comprise a reinforcing spun fibre and a coating layer made of elastomeric material and/or other layers.

TL;DR: In this paper, the glass transition temperature (Tg) of core-shell particles-toughened poly(methyl- methacrylate) (CSPTPMMA) and NRTPMMA, which are basically the PMMA/elastomer blends with different concentrations of elastomer heterogeneously distributed in the samples, was investigated by means of differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), and microindentation technique (MT).
Abstract: Glass transition temperature (Tg) of core-shell particles-toughened poly(methyl- methacrylate) (CSPTPMMA) and natural rubber-toughened PMMA (NRTPMMA), which are basically the PMMA/elastomer blends with different concentrations of elastomer heterogeneously distributed in the samples, was investigated by means of differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and microindentation technique (MT). Microhardness (H) of the samples was measured using MT. Core-shell particles (CSP) with a rubbery shell and natural rubber (NR) were used as reinforcing materials for the production of compatible and incompatible blends, respectively. Results reveal a good correlation of the glass transition temperature (Tg) obtained from DSC and DMA, and that deduced from MT. The H-value of each sample is compared with its Tg-value. Increase of Tg with the increase of H, which is a general behavior of polymers, is not maintained in the both blends investigated. Contrary to expectation, H is shown to decrease with increasing glass transition temperature in case of CSP-toughened compatible blends while it decreases with the decrease of Tg-value only in case of NR-modified incompatible blends for lower NR concentration (<1 wt%) and does not depend on Tg for rubber content higher than 1 wt%.

TL;DR: In this paper, a claim is included for composite comprising (I), which is heat-sealed to a substrate (1) made of coated or uncoated paper or synthetic paper.
Abstract: Multi-layered sheet (I) comprises: a main layer (4) made of polypropylene; a peeling layer (3) containing a polyolefin plastomer (30-80 wt.%) having a density of 0.85-0.89 g/cm 3>and a polypropylene (20-70 wt.%) having a melting point of 100-150[deg] C in differential scanning calorimetry. An independent claim is included for composite comprising (I), which is heat-sealed to a substrate (1) made of coated or uncoated paper or synthetic paper.
