Effect of viscoelastic and surface properties on tack, peel adhesion and shear strength of polymer blends applied as hot melt pressure sensitive adhesive models comprising tackifying agents of various chemical nature

eXPRESS Polymer Letters, 2020
Viscoelastic and surface properties of polymer blends prepared as models of hot melt pressure sensitive adhesives (HMPSA) were investigated and the correlation to tack, peel, and shear adhesion properties was discussed.

Oxygen-barrier films based on low-density polyethylene/ ethylene vinyl alcohol/ polyethylene-grafted maleic anhydride compatibilizer [PDF]

Polyolefins Journal, 2016
In this research, high oxygen-barrier films were organized based on low-density polyethylene (LDPE)/ ethylene vinyl alcohol (EVOH)/ polyethylene-grafted maleic anhydride (LDPE-g-MA) compatibilizer. The effects of 10–30 wt. % EVOH and 0–10 wt. % LDPE-g-MA

PMMA/SAN and SAN/PBT nanoblends obtained by blending extrusion using thermodynamics and microrheogy basis

eXPRESS Polymer Letters, 2014
Styrene-Acrylonitrile (SAN) copolymer has been blended to poly(methyl methacrylate) (PMMA) and to poly(butylene terephthalate) (PBT) to obtain polymer nanoblends based on thermodynamics and microrheological aspects.

Luminescent biodegradable polycaprolactone materials prepared by blending with bio-based hyperbranched polymers

eXPRESS Polymer Letters, 2022
It is the pursuit to give biodegradable polycaprolactone (PCL) luminescence properties while maintaining its biocompatibility in a feasible way. For this purpose, bio-based luminescent furan-terminated hyperbranched polymers (HBPFs) have been synthesized,

Relationship between the mechanical properties of epoxy/PMMA-b-PnBA-b-PMMA block copolymer blends and their three-dimensional nanostructures

eXPRESS Polymer Letters, 2017
Nanostructures of diglycidyl ether of bisphenol-A epoxy/poly(methyl methacrylate)-b-poly(n-butyl acrylate)-b-poly(methyl methacrylate) (PMMA-b-PnBA-b-PMMA) triblock copolymer (BCP) blends were studied in relation to their mechanical properties.

Thermal mending in novel epoxy/cyclic olefin copolymer blends

eXPRESS Polymer Letters, 2020
In this paper, the thermal mending potential of a cyclic olefin copolymer (COC) in a thermosetting matrix was evaluated for the first time. Epoxy/COC blends were prepared by mechanically mixing a COC powder (particle size lower than 300 μm) at different ...

A Thorny Problem? Spinodal Decomposition in Polymer Blends

Macromolecules, 2020
R into mixtures of polymers developed rapidly in the 20th century, soon after Staudinger’s seminal paper on the long chain nature of the molecules. Interest was driven both by intellectual curiosity about whether, why, and how such very large molecules ...

Creation of fully degradable poly(lactic acid) composite by using biosourced poly(4-hydroxybutyrate) as bioderived toughening additives

eXPRESS Polymer Letters, 2022
The inherent brittleness of poly(lactic acid) (PLA) limited its practical applications, so toughening modification was necessary. Poly(4-hydroxybutyrate) (P4HB) is fully biosourced and biodegradable polyester with the advantages of high strength and good
