Olefins, or alkenes, form naturally in many living things. According to Bruce Hathaway’s book, Organic Chemistry, the nutrient beta-carotene is a natural olefin found in carrots. It contains a chain of carbon atoms doubly and singly bonded together with a ring structure close to either end. The simple olefin, ethylene, promotes the ripening. Polymers degrade by several different mechanisms, depending on structure and exposure conditions. Degradation results from an irreversible change which leads eventually to failure. The most common types of degradation occur through chemical reactions, but there are a few important examples of degradation resulting only from physical changes.
In this work, the influence of preshearing on crystallization of olefin block copolymer (OBC) was systematically investigated. It was found that upon an interval of melt preshear the crystallization rate of OBC was prominently elevated which was evidenced by both nonisothermal and isothermal crystallization results. The lamellar thickness of OBC increased and the size of spherulites decreased Cited by: 1. Semi‐crystalline Polymers: From Lattices to Superstructures Chain Structure and Crystallization Speed.

Olefin block copolymer (OBC), with its low hard segments, can form unique space-filling spherulites other than confined-crystallization morphologies, mainly due to its weak phase-separation.

The structure of crystalline polymers is discussed briefly in Section and has been reviewed in standard textbooks. 1,2 Crystalline polymers are found in a variety of morphological forms ranging from single crystals to semicrystalline polymers in which the non-crystalline component can be either rubbery or glassy.
In addition. The present invention generally concerns thermoplastic elastomer compositions comprising blends of chlorinated polyethylene and a crystalline olefin polymer. The present invention also concerns preparation of said compositions by dynamic vulcanization or by a sequential combination of dynamic vulcanization and static curing.

These polymers have been covered inFile Size: KB. Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties.
While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection molding. The single-chain properties and self-assembly behavior in dilute solution of olefin block copolymers obtained by chain-shuttling technology and consisting of alternating crystallizable and amorphous ethylene/1-octene blocks were investigated by pinhole and focusing small-angle neutron scattering techniques, optical microscopy in bright-field and crossed-polarizer modes, and differential Cited by: 4.
The first unsubstituted olefin-linked covalent organic framework, termed COF, was made by linking 2,4,6-trimethyl-1,3,5-triazine (TMT) and 4,4′-biphenyldicarbaldehyde (BPDA) through Aldol condensation.

Chain shuttling polymerization is a dual-catalyst method for producing block copolymers with alternating or variable desired effect of this method is to generate hybrid polymers that bear the properties of both polymer chains, such as a high melting point accompanied by high elasticity.
Crystalline block copolymers of ethylene and propylene (which are plastics distinguished from amorphous, random ethylene-propylene elastomers) can also be used. Included among the polyolefin resins are the higher alpha-olefin modified polyethylenes and polypropylenes (see, "Polyolefins," N.
V. Boenig, Elsevier Publishing Co., N. Y. ).As a type of novel semi-crystalline block copolymers, the final properties of olefin block copolymers (OBCs) greatly depend on the crystalline and phase-separated structures.
