Scandium Half-Metallocene-Catalyzed Syndiospecific Styrene Polymerization and Styrene−Ethylene Copolymerization:  Unprecedented Incorporation of Syndiotactic Styrene−Styrene Sequences in Styrene−Ethylene Copolymers

, 2016
On treatment with 1 equiv of [Ph3C][B(C6F5)4], the scandium half-sandwich bis(alkyl) complex (C5Me4SiMe3)Sc(CH2SiMe3)2(THF) showed extremely high activity (up to 1.36 × 104 kg of sPS/(mol Sc·h)) and syndiospecificity (rrrr > 99%) for the polymerization ...

Viscoelastic Properties of Multiple Network Polymers. IV. Copolymers of Styrene and Divinylbenzene

, 1967
Copolymerization of vinyl and divinyl monomer is a typical method for preparing a network polymer. A multiple network structure, in which one network entangles with another, is supposed to be produced when a network polymer is swollen in the monomer ...

Synthesis and Characterization of β‐Myrcene‐Styrene and β‐Ocimene‐Styrene Copolymers

The structure-properties relationships of sustainable materials derived from biomass-based monomers are investigated, focusing on hybrid styrene/terpene-based copolymers with blocky microstructures, such as beta-myrcene- and beta-ocimene-styrene ...

Studies of Crosslinked Styrene–Alkyl Acrylate Copolymers for Oil Absorbency Application. I. Synthesis and Characterization

, 2000
The prepolymers for a novel oil absorbent were synthesized by copolymerizing styrene with 2-ethylhexyl acrylate (EHA), lauryl acrylate (LA), lauryl methacrylate (LMA), and stearyl acrylate (SA).

COPOLYMERS OF STYRENE AND CHLORANIL

, 1950
The copolymerization of styrene and chloranil in the presence of benzoyl peroxide is described. The molecular weights of the copolymers were determined by osmotic pressure measurements and found to be between 9,000 and 30,000 for the different fractions;

Synthesis of biodegradable styrene copolymers

, 2017
Polystyrene (PS), a versatile polymer with many applications (e.g. packaging) representing about 10% of the total annual polymer consumption, shows practically no biodegradability.

Flexibilized styrene-N-substituted maleimide copolymers. I. Multiblock copolymers prepared from styrene-maleimide telechelics and polytetrahydrofuran

, 2000
Telechelic copolymers of styrene and different N-substituted-maleimides (SMIs) with a molecular weight of 2000-8000 g/mol were synthesized using the starved-feed-reactor technique and were nearly bifunctional when the monomer feed had a high styrene ...

Nanostructured ethylene–styrene copolymers

, 2014
A judicious choice of a polyinsertion catalyst and monomer feed composition allows the one-pot synthesis of ethylene–styrene copolymers with an unprecedented structure, containing an isotactic polystyrene (iPS) block joined to an isotactic ethylene-alt ...
