Review: degradation-induced embrittlement in semi-crystalline polymers having their amorphous phase in rubbery state
TL;DR: In this article, the degradation-induced embrittlement mechanism in semi-crystalline polymers having their amorphous phase in rubbery state is reviewed and a simple relationship expressing the chemicrystallization yield for a given polymer structure is proposed.
Journal ArticleDOI
Mechanism of degradation induced embrittlement in polyethylene
TL;DR: In this paper, the authors studied the embrittlement of polyethylene films in air at 80°C and 90°C, and proposed a chain scission mechanism to induce chemicrystallization.

Outdoor and accelerated laboratory weathering of polypropylene: A comparison and correlation study
TL;DR: In this article, the degradation behaviors under outdoor and accelerated laboratory weathering conditions of isotactic polypropylene (iPP) were compared, aiming to establish a correlation between both weathering types.
Journal ArticleDOI
Challenges and opportunities of solvent-based additive extraction methods for plastic recycling
TL;DR: The feasibility of additives removal depends strongly on the type of additive and plastic and also on the extraction conditions, so in the best-case scenario at least 70% of solvent recovery is required to extract plasticizers via dissolution-precipitation with tetrahydrofuran.
Journal ArticleDOI
A general solution of the closed-loop kinetic scheme for the thermal oxidation of polypropylene
TL;DR: In this article, a general solution of the closed-loop kinetic scheme for the thermal oxidation of polypropylene polymers is presented in which no assumptions are made concerning the concentration of oxygen, the kinetic chain length, the ratio of termination rate constants or the existence of a steady-state for concentration of radicals.

Molecular model of drawing polyethylene and polypropylene.
TL;DR: In this paper, it was shown that high molecular weight samples with many interlamella links exhibit a smaller draw ratio than lower molecular weight material, and that the three stages are intermixed in the neck.
