Natural rubber/styrene-butadiene rubber blends prepared by solution mixing: Influence of vulcanization temperature using a Semi-EV sulfur curing system on the microstructural properties [PDF]

, 2017
Blends of natural rubber (NR) and styrene-butadiene rubber (SBR) were prepared by solution mixing and vulcanized with sulfur and accelerator in a Semi-EV system at 433 K and 443 K in order to study the vulcanization kinetic and the influence of ...

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

Advanced Functional Materials, EarlyView.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

The co-pyrolysis of flame retarded high impact polystyrene and polyolefins [PDF]

, 2007
The co-pyrolysis of brominated high impact polystyrene (Br-HIPS) with polyolefins using a fixed bed reactor has been investigated, in particular, the effect that different types brominated aryl compounds and antimony trioxide have on the pyrolysis ...

4D Printing of Self‐Immolative Polymers

Advanced Functional Materials, EarlyView.
The integration of self‐immolative polymers (SIPs) into light‐based 3D printed structures is presented as a new “living” 4D printing strategy. By exploiting their metastability and stimuli‐responsiveness, SIP‐containing printed objects can undergo rapid and triggered degrowth under ambient conditions and subsequent regrowth through polymer ...

Micro- vs. macro-phase separation in binary blends of poly(styrene)-poly(isoprene) and poly(isoprene)-poly(ethylene oxide) diblock copolymers [PDF]

, 2001
In this paper we present an experimentally determined phase diagram of binary blends of the diblock copolymers poly(styrene)-poly(isoprene) and poly(isoprene)-poly(ethylene oxide). At high temperatures, the blends form an isotropic mixture. Upon lowering

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications

Advanced Functional Materials, EarlyView.
Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Effect of the method of emulsion preparation on the kinetic characteristics of styrene emulsion polymerization

Тонкие химические технологии, 2011
The introduction of ionic and non-ionic surfactants in different phases of the system significantly influences the colloidal-chemical characteristics of surfactants, the properties of the initial emulsion, the kinetics of styrene polymerization, the size
