Polyethylene glycol dimethacrylate

Allyl methacrylate and allyl acrylate are difunctional monomers, triallyl phosphate is a trifunctional monomer, and polyethylene glycol dimethacrylate is a polyfunctional monomer. All these lead to cross-linked graft copolymers.

The manufacture of optically active L-a-amino acids from racemic amino acid amides was shown by Mitsubishi Gas Chemical, Japan [117]. In this process different microorganisms were immobilized on polymers made from (meth)acrylic acid esters or urethane acrylates and applied for the stereoselective hydrolysis of racemic amides (Scheme 43). o/L-Leucinamide (rac-136), for example, can be hydrolyzed with Mycoplana bullata cells immobilized on polyethylene glycol dimethacrylate-AT,N -methylenebisacrylamide copolymer at 30 C to produce i-leudne (l-137) over 3,000 h. 

Emulsions of polyvinyl acetate and polyalkyl acrylates have been used as tub caulking compositions, spackling compounds and as building sealants.22 Acrylic sealants which harden in the presence of powdered iron or copper meet Federal Specifications TT-S-00230C. 27 Liquid monomers, such as polyethylene glycol dimethacrylate and butyl alpha—cyanoacrylate have been used as room temperature curing sealants.22 22. 

The first anaerobic adhesives were made at the General Electric Company by aeration of a polyethylene glycol dimethacrylate. This Anaerobic Permafil required continuous aeration to prevent hardening [7]. Although a number of internal applications had been identified, the problems associated with shipping and storage made the product so impractical that the company decided to discontinue its manufacture. 

These chemicals harden between metal parts in the absence of air. They are resistant to shock and vibration, and are used for making locking threads of screws and as sealants, structural adhesives, and as photoresists in photolithography. They are a fairly common cause of sensitisation in the electronics industry. Polyethylene glycol dimethacrylate is the most frequently reported sensitiser [59-62]. The acrylate sealants may also contain stabilisers, accelerators, and other additives which can also cause ACD [62].
