CH3CH2CHCHCH3 What are the monomers and polymers of protein? Show the repeating unit that would be obtained in the polymerization of the following monomers:...
The IUPAC name is poly(1-carboxyethylene). They may be homopolymers of acrylic acid, or crosslinked with an allyl ether of pentaerythritol, allyl ether of sucrose, or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains ...

What is the difference between anionic, cationic, and gre radical polymerization? What spectroscopic method is used to distinguish the (CH_3)_2CHCH_2COH? How are glycolipids different from glycerophospholipids? What is the difference between shielding and penetration?
SBS plastic usually refers to butadiene and styrene as monomers, cyclohexane as solvent, n-butyllithium as initiator, and tetrahydrofuran as activation As a coupling agent, silicon tetrachloride is a high molecular polymer prepared by anionic polymerization. Styrene-butadiene-styrene block copolymer (SBS...
The influence of increasing conversion on structure and topology of homoand copolymers is illustrated. Chainゞrowth polymerizations, such as radical polymerization or living anionic polymerizations of vinyl monomers, condensative chain polymerization, two and threeヾimensional stepゞrowth polymerizations...
Generally, radical initiation is used (including living polymerization methods), but anionic polymerization of PMMA can also be performed. To produce 2.2 lb. of PMMA, about 4.4 lb. of petroleum is needed. All PMMA commercially produced by radical polymerization is atactic (a polymer exhibiting no...
Butadiene rubber BR9000 is a high-cis polybutadiene rubber, which is a homopolymer obtained by anionic polymerization of butadiene in a hydrocarbon solvent using a nickel-based catalytic system. It is a lightcolored block solid with high elasticity and cold resistance, as well...
