A well-defined amphiphilic polymer co-network from precise control of the end-functional groups of linear RAFT polymers
Linear polystyrene (PS) with well-defined molecular structure and accurate numbers of bromo groups on both ends were synthesized via multiple-step alternative RAFT polymerization of N-bromopropyl maleimide and bpinene monomers. The bromo end groups were transformed into the azido moieties via nucleophilic substitution. The reaction of as-synthesized linear PS having a named number of azide group...

A Well-Defined Amphiphilic Polymer Conetwork from Sequence Control of the Cross-Linking in Polymer Chains
Well-defined amphiphilic polymer conetworks with precisely controlled number and position of cross-links were prepared by copper-catalyzed azide-alkyne cycloaddition (CuAAC) using linear polystyrene (PS) and poly(ethylene glycol) (PEG) as the building blocks. In this approach, linear polystyrene containing a specific number of bromo groups at a predetermined position of polymer chains was synthe...

Thermoplastic Polyester Elastomer Composites Containing Two Types of Filler Particles with Different Dimensions: Structure Design and Mechanical Property Control
Composite Structures, 2018, 197C, 21-27
ABSTRACT:
Particle reinforcement is a common approach to improve mechanical properties of thermoplastic polyester elastomer (TPEE). The improvement of strength is commonly accompanied by an evident increase of Young''''''''s modulus, which is against the usage of TPEE as the elastomer material, however. The high-strength TPEE composit...

An Efficient Organic Additive to Control the Crystallization Rate of Aliphatic Polyketone: A Non-isothermal Crystallization Kinetics Study
Three types of organic compounds—two carboxylic acids and an anhydride, were used as additives for polyketone (PK). The effect of the additive structure and their feed ratios on the melting temperature, crystallization temperature, and crystallization rate of PK were studied. We found that the crystallization temperature could be reduced significantly by introducing a small quantity of organic ...

Control of molecular weight distribution for polypropylene obtained by commercial Ziegler–Natta catalyst: effect of temperature
Polymerization of propylene was carried out by using MgCl2-supported TiCl4 catalyst in conjunction with triethylaluminium (TEA) as cocatalyst. The effect of polymerization temperature on polymerization of propylene was investigated. The catalyst activity was influenced by the polymerization temperature significantly and the maximum activity of the catalyst was obtained at 40 C. With increasing ...

Control of Molecular Weight Distribution for Polypropylene Obtained by Commercial Ziegler-Natta Catalyst: Effect of Electron Donor
Polymerization of propylene was carried out using a MgCl2-supported TiCl4 catalyst in conjunction with triethylaluminium (TEA) as the cocatalyst and various types of alkoxy silane compounds as an external donor. The effect of the external donor on the performance of the catalyst with different internal donors was investigated. The polydispersity index (PDI) of polypropylene (PP) obtained with th...

Control of Molecular Weight Distribution for Polypropylene Obtained by a Commercial Ziegler–Natta Catalyst: Effect of a Cocatalyst and Hydrogen
The polymerization of propylene was carried out with an MgCl2-supported TiCl4 catalyst (with diisobutyl phthalate as an internal donor) in the absence and presence of hydrogen (H2) as a chain-transfer agent. Different structures of alkylaluminum were used as cocatalysts. The effects of the alkyl group size of the cocatalyst, H2 feed, and feed time on the propylene polymerization behaviors were i...
