Tetraethylene glycol dimethacrylate

The DADC monomer has been copolymerized with small amounts of polyfunctional methacryflc or acryflc monomers. For example, 3% triethylene glycol dimethacrylate was used as a flexibiflzing, cross-linking agent with a percarbonate as initiator (26). CR-39 and diethylene glycol diacrylate containing isopropyl percarbonate were irradiated with a mercury lamp to a 92% conversion and then cured at 150°C (27). By a similar two-step process DADC was copolymerized with methyl methacrylate and tetraethylene glycol dimethacrylate (28).

An approximately linear relationship of S as a function of k1/3 is also exhibited by hydrophilic macronet crosslinked polymers as indicated by the results deduced via a similar reconsideration of the swelling and molecular weight data reported by Refojo [145], who studied swelling of 2,3-dihydroxypropyl metha-crylate-co-tetraethylene glycol dimethacrylate polymers in water. 

Two important departures from standard procedures should be noted (1) all monomers contained 0.4% (W/V) of cross-linking agent tetraethylene glycol dimethacrylate necessary to form the IPN. (2) No new soap was added for the second stage polymerization to discourage the formation of new particles. Total polymer concentration of the completed latexes was about 30% (W/V). 

IPN s of 54/46 poly(methyl methacrylate)/poly(ethyl acrylate) were prepared by both the latex and bulk (10) routes. Both IPN s contained 0,4% (W/V) tetraethylene glycol dimethacrylate (TEGDM) crosslinking agent in each polymer. Samples of the latex IPN were film formed on glass petri dishes, All samples were vacuum dried at 60°C to constant weight.

Petropoulos (28) carried out a kinetic study of the photoinitiation of bulk tetraethylene glycol dimethacrylate pdymerization by desyl aryl sulphides. 

Sequential IPNs are started with one polymer that is already cross-linked. It is swollen, and a monomer along with an initiator and a cross-linking agent are added and polymerized in place. A typical example (37) is an elastomer such as butadiene or ethyl acrylate cross-linked with divinylbenzene as the first polymer. The monomer that is polymerized in the swollen polymer is styrene or methyl methacrylate cross-linked with divinylbenzene or tetraethylene glycol dimethacrylate. The initiator is potassium for butadiene, and benzoin for the other monomers.

Baldwin and Lees (18) disclosed that VTBN with THP methacrylate can serve to optimize a set of properties based on shear (collar/pin and lap joint) and impact strengths. This balance appears to occur at reactive liquid rubber levels of 7.5-10.0%. These improvements occurred without detriment to storage stability and subsequent curability of the composition. Catena (19) essentially verifies that comparable activity is obtained when VTBN serves as a 10% monomer replacement in anaerobic formulations based on tetraethylene glycol dimethacrylate.
