Tripropyleneglycol diacrylate

The influence of polyfunctional monomers—tripropyleneglycol diacrylate (TPGDA), TMPTA, TMPTMA, TMMT, and TAG on the stmctural changes of fluorocarbon terpolymer poly(vinylide-nefluoride-co-hexafluoropropylene-co-tetrafluoroethylene) has been investigated [425]. The ATR-IR studies show that the absorbance due to the double bond at 1632 cm decreases both in the... 

The photoinitiator selected for this study was 1-benzoyl cyclohexanol (Irgacure 184 from Ciba Geigy), a compound known for its high initiation efficiency and the weak coloration of its photoproducts. The multifunctional monomer was an epoxy-diacrylate derivative of bis-phenol A (Ebecryl 605 from UCB). A reactive diluent, tripropyleneglycol diacrylate, had to be introduced in equal amounts, in order to lower the viscosity of the formulation to about 0.3 Pa.s. 

Affinito [2] vapor coated hexanediol diacrylate, trimethylolpropane triacrylate, and tripropyleneglycol diacrylate hquid monomers at roughly 80°C and 1 X 10 torr onto polyethylene terephtholate and then radiation polymerized the surface using electron beam radiation.

Three photopolymerizable primer monomers, namely the linear hexanediol diacrylate (HDDA), the branched trimethylol propane triacrylate (TMPTA), and the linear tripropyleneglycol diacrylate (TPGDA), and a model of a linear unsaturated polyester/ alkyd varnish repeating unit were used for the study. A model of the two top chains of an elementary cellulose I crystallite was used as a substrate, the refined conformation of which had already been reported [12].
