Elastic substantially linear olefin polymers
TL;DR: Elastic substantially linear olefin polymers are disclosed in this paper which have processability similar to highly branched low density polyethylene (LDPE), but the strength and toughness of linear LDPE, and can also have from 0.01 to 3 long chain branches/1000 carbons along the polymer backbone.

Catalytic Production of Olefin Block Copolymers via Chain Shuttling Polymerization
TL;DR: A catalytic system that produces olefin block copolymers with alternating semicrystalline and amorphous segments by varying the ratio of α-olefin to ethylene in the two types of blocks is reported, which maintains excellent elastomeric properties at high temperatures.

TL;DR: In this article, a multi-block copolymer is defined for use in forming a multinode copolym, containing two or more segments or blocks differing in chemical or physical properties, and a polymerization process using the same, and the resulting polymers, wherein the composition comprises the admixture or reaction product resulting from combining: (a) a first metal complex olefin polymerization catalyst, (b) a second metal complex OLEF polymerisation catalyst capable of preparing polymers differing from the polymer prepared by catalyst under equivalent polymerization conditions, and (

Classification of homogeneous ethylene‐octene copolymers based on comonomer content
TL;DR: In this article, a classification of copolymers with high and low comonomer content is presented. But, as the comonomers increase, the corresponding tensile behavior changes from necking and cold drawing typical of a semicrystalline thermoplastic to uniform drawing and high recovery characteristic of an elastomer.
