Thermally enhanced pristine polyolefins: fundamentals, progress and prospective
Journal of Materials Research and Technology, 2020 The low thermal conductivity of polymers hinders their use in applications requiring high thermal conductivity such as electronic packaging, heat exchangers, and thermal management devices. Polyethylene and polypropylene (polyolefins) account for ∼55% of

A co-anchoring strategy for the synthesis of polar bimodal polyethylene
Nature Communications, 2023 Polar functional groups can improve the polymer properties of polyolefins but also poison the metal catalyst used during the polymerization reaction.

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 ...

MFC concept as a possible solution for closed-loop recycling of food packaging trays [PDF]
, 2020 Flexible plastic films from food packaging trays make up one of the largest fractions of the plastic waste stream and recycling is one of the most important actions to deal with this fraction, reducing the impact of these plastics on the environment ...

A general kinetic model for the photothermal oxidation of polypropylene [PDF]
, 2014 A general kinetic model for the photothermal oxidation of polypropylene has been derived from the basic auto-oxidation mechanistic scheme in which the main sources of radicals are the thermolysis and photolysis of the most unstable species, i.e ...

Thermooxidative aging of polydicyclopentadiene in glassy state [PDF]
, 2014 Thermal aging of thin films of unstabilized polydicyclopentadiene (pDCPD) at several temperatures ranging from 120 to 30 C was investigated by means of carbonyl build up by FTIR with ammonia derivatization, double bond titration, mass uptake measurement ...

Comparison of stabilization by Vitamin E and 2,6-di-tert-butylphenols during polyethylene radio-thermal-oxidation [PDF]
, 2014 This paper reports a compilation of data for PE+Vitamin E and 2,6-di-tert-butylphenols oxidation in radio-thermal ageing. Data unambiguously show that Vitamin E reacts with P° and POO° whereas 2,6-di-tert-butyl phenols only react with POO°.
