Summary
A new adhesive platform rapidly bonds diverse polymers at room temperature using a simple process. This innovation offers cost savings and faster production for industries like automotive and aerospace.
Area of Science:
- Materials Science
- Polymer Chemistry
- Adhesion Science
Background:
- Adhesives are crucial in manufacturing, but bonding many polymers requires complex, time-consuming methods.
- There is a need for rapid-cure adhesives that work under ambient conditions with simple procedures.
Purpose of the Study:
- To develop a novel adhesive platform for bonding a wide range of commodity polymers.
- To achieve rapid curing, minimal surface preparation, and robust adhesion at room temperature.
Main Methods:
- Utilized a trialkylborane-ligand complex and isocyanate decomplexing agent to initiate (hydrogen) atom transfer and free-radical polymerization.
- Formulated an air-stable, bulk adhesive based on poly(isobornyl acrylate).
- Investigated process-property relationships, lap-shear performance, and failure mechanisms.
Main Results:
- Successfully bonded seven diverse polymer substrates including PTFE, polyethylene, and PVC in approximately 30 minutes.
- The adhesive operates at room temperature with minimal surface preparation.
- Incorporation of polyhedral oligomeric silsesquioxane (POSS) enhanced the glass-transition temperature to ~120 °C.
Conclusions:
- The alkylborane-initiated adhesion platform provides a rapid and versatile solution for polymer bonding.
- This technology has potential applications in automotive, aerospace, and marine sectors for efficient manufacturing and structural adhesion.

8.7K
In addition to the oxymercuration–demercuration method, which converts the alkenes to alcohols with Markovnikov orientation, a complementary hydroboration-oxidation method yields the anti-Markovnikov product. The hydroboration reaction, discovered in 1959 by H.C. Brown, involves the addition of a B–H bond of borane to an alkene giving an organoborane intermediate. The oxidation of this intermediate with basic hydrogen peroxide forms an alcohol.

01:20Anionic Chain-Growth Polymerization: Overview
2.2K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

Overview
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...

00:57Cationic Chain-Growth Polymerization: Mechanism
2.4K
The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the...

00:53Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)
2.0K
Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

8.1K
The conversion of alkenes to macromolecules called polymers is a reaction of high commercial importance. The structure of the polymer is defined by a repeating unit, while the terminal groups are considered insignificant. The average degree of polymerization represents the number of repeating units in the polymer molecule and is denoted by the subscript n.
