Autoclave foaming and steam-chest molding of polypropylene/polybutene-1 blend bead foams and their crystallization and mechanical properties

Journal of cellular plastics (Print), 2023
Expanded polypropylene (EPP) foams have showed wide applications in our daily life, such as automotive and packaging. Usually, autoclave foaming combined with steam-chest molding is the main artwork to prepare the high-precision EPP foam products ...

Composition analysis of polybutenes

Journal of Chromatography A, 1963
Abstract The structure and composition of polyolefins made from pure isobutylene and from isobutylene diluted with various amouts of other light olefins have been investigated. The techniques used were nuclear magnetic resonance and combined anaerobic pyrolysis and gas chromatography.

Further Promoting Form II‐To‐Form I Phase Transition in Low‐Molecular‐Weight Polybutene‐1 by Addition of Heating/Cooling Cycles Into Nucleation Stage of Form I

Journal of Polymer Science
Despite employing a two‐step annealing method, Form II to Form I phase transitions in some low‐molecular‐weight polybutene‐1 (LMWPB‐1) samples are still slow.

Retarding crystal transitions of polybutene-1 in blends

CrysteEngComm, 2023
In this study, copolymers of 1-butene with allyltrimethylsilane (TMAS) were synthesized via rac-ethylenebis (indenyl) zirconium chloride (rac-Et(Ind)2ZrCl2)/methylaluminoxane (MAO) catalyst.

Self‐Nucelation Effect on Crystallization of Double Crystalline Polypropylene‐b‐Polybutene Block Copolymers

Macromolecular rapid communications
Self‐nucleation effect of crystalline polymers originates from the intrinsic in‐complete relaxation of crystallization‐associated ordered structure and plays a crucial role in accelerating crystallization without adding the extra nucleating agents.

Chain dimension and crystallization temperature affected II-I transition of isotactic polybutene-1

CrysteEngComm, 2022
Isotactic polybutene-1 (iPB-1) usually crystallizes into Form II from melt first and then spontaneously transforms into Form I that with outstanding properties.
