“…[2,3] In the EP terpolymer, the third monomer remains mainly dienes, higher α-olefins. [2,[4][5][6][7][8][9][10] Upon polymerization, there might still remain unsaturated bonds in the terpolymer. [11] These terpolymers with a large proportion of ethylene or propylene (or other olefins) and a small amount of a monomer whose molecule contains more than one double bond also exhibits good elastic and mechanical properties.…”

“…EP copolymers are generally processed for excellent elastomeric properties by two methods: vulcanization and peroxide curing, where in peroxide curing, the unsaturated double bond in the macromolecule has the ability to open the door for good product. [3,7] Despite reported literature on terpolymers, there is still required investigation about the terpolymerization of ethylene-propylene and a monomer that contains unsaturated bonds to substantially subject to react for vulcanization or peroxide curing.

Polyolefin copolymers have been an important commercial product since their invention. Hence, it is crucial to study their co‐ and terpolymers due to their extensive use. In this paper, in situ synthesis of ethylene‐propylene (EP) copolymer, its terpolymer with styrene, and composites with nickel‐chromium (NiCr) layered double hydroxide (LDH) has been reported along with their thermal properties. Styrene had a significant impact on the activity, increasing the yield by 195% and 235% with an addition of 0.5 and 1.0 mL styrene, respectively, compared to neat EP. The crystallinity, melting temperature, and thermal stability decreased due to styrene; nevertheless, it performed better compared to a similar work of terpolymer where α‐olefin was the third monomer. The incorporation of NiCr LDH as a drop‐in filler during in situ polymerization affected adversely the thermal stability of the terpolymer. However, the ultrasonication treatment improved the thermal stability of the final product.

By use of a THF‐containing trimethylsilylmethyl scandium catalyst system (C5Me4SiMe3)Sc(CH2SiMe3)2(THF)/[Ph3C][B(C6F5)4], the multi‐component copolymerization of 10‐bromo‐1‐decene (BrDC) with ethylene, propylene, and dienes has been achieved to afford a new family of bromine‐functionalized polyolefins with controllable composition and high molecular weight. The copolymerization of BrDC with ethylene afforded the well‐defined BrDC–ethylene copolymers with high BrDC incorporation (up to 12 mol%) and high molecular weight (Mw > 100 kg mol−1). The terpolymerization of propylene, ethylene with BrDC afforded random ethylene–propylene–BrDC terpolymers with controllable bromine content (2 ~ 11 mol%), high molecular weight (Mw > 100 kg mol−1) and low glass transition temperature (Tg = −51 °C ~ −67 °C). Moreover, the tetrapolymerization of ethylene, propylene, BrDC, and ethylidene norbornene or conjugated dienes such as isoprene and myrcene has been achieved for the first time to afford selectively the bromine‐functionalized ethylene–propylene–diene rubbers containing various types of double bonds.
