This study investigates the influence of material properties and foaming temperature on the
cellular structure of foams produced by batch foaming of linear, branched and nucleated …

The influence of two peroxides (peroxydicarbonate/dilauroyl peroxide) with various
concentrations (10–200 mmol/kg PP) and their effective opportunity to introduce long chain …

Long‐chain branching plays an important role in the performance of polyolefins (POs). The
existence of a very small amount of long‐chain branches (LCBs), ie,< 1 per 10 000 carbons …

Linear polypropylene (PP) exhibits poor foamability because of its inherently low melt
strength. Incorporation of long-chain branches is a common approach to increase melt …

A novel strategy for introducing long chain branches (LCB) on commercial polypropylene
(PP) was described using an extender agent, poly (hexamethylendiamine-guanidine …

Long-chain branching (LCB) is known as a suitable method to increase the melt strength
behavior of linear polypropylene (PP), which is a fundamental weakness of this material …

A grafting monomer (p-(3-butenyl) styrene, BS)) containing two carbon–carbon double-
bonds with different reactivity was used in melt radical reaction to prepare long chain …

Reactive extrusion using dicumyl peroxide (DCP) and a tri-functional coagent, triallyl
trimesate (TAM) is implemented to introduce long-chain branching (LCB) in poly (lactic …

Attapulgite (ATT) has never been used as a barrier additive in polypropylene (PP). As a filler,
ATT should be added in high content to PP. However, that would result in increased costs …

A mathematical model was established to simulate the bubble growth process during
foaming of polypropylene (PP) by carbon dioxide, taking into account of a wide range of …
