Butanediol diacrylate

A stock mixture (50 g) of monomers suitable for preparing intraocular lens material was prepared by thoroughly mixing 2-phenylethyl acrylate (66 wt%), 2-phenylethyl methacrylate (30.5 wt%), and 1,4-butanediol diacrylate (3.5 wt%).

For synthesis of one lead polymer, poly(5-amino-1 -pcntanol-co-1,4-butancdiol diacrylate) (referred to as C32), 5-amino-l-pentanol (Aldrich) and 1,4-butanediol diacrylate (Scientific Polymer Products, Inc.) are required. Additional amine and diacrylate monomers can be purchased and used following the same protocol to create structurally diverse polymers that are useful for gene delivery. These monomers can be purchased from Aldrich (Milwaukee, WI, USA), Scientific Polymer Products, Inc. (Ontario, NY, USA), TCI (Portland, OR, USA), Pfaltz Bauer (Waterbury, CT, USA), Matrix Scientific (Columbia, SC, USA), and Dajac Monomer-Polymer (Feasterville, PA, USA). 

Add acrylate monomer to amine monomer at an amine/diacrylate stoichiometric ratio of 1.2 1. For polymer C32, add 640 mg of 1,4-butanediol diacrylate to the 400 mg of 5-amino-l-pentanol.

Langer [3] coupled 1,4-butanediol diacrylate with poly(A, A -dimethylethyl-enediamine), (III), piperazine, and 4,4 -trimethylenedipiperidine to prepare poly(p-amino esters) that were particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes were also prepared. Hubbell [4] and Zhao [5] prepared polymeric biomaterials by the nucleophilic addition of cysteine, (IV), and polyethylenimine, (V), respectively, to cx,p-unsaturated macromolecular diacrylates. 

A small flask was charged with 1,4-butanediol diacrylate (0.45 mmol) dissolved in 2ml of CH2CI2 then treated with l,3-dimesityl-4,5-dihydroimidazol-2-ylidene)ben-zylidene-tricyclopentyl-phosphine ruthenium(II) dichloride (2.7 mg) and cyclooctene (0.45 mmol), the total monomer-to-catalyst ratio being 290 1. The mixture was... 

An unusual process features a spun polythene band ich has been impregnated with blended acrylic latices, e.g, containing 1,4-butanediol diacrylate, ethyl acrylate and acrylic acid in 1 component, and l,4 butanediol diacrylate, butyl acrylate, acrylic acid and NllAM in a second. 1 of the photosensitiser, benzoin isopropyl ether is also present. The impregnated band is drawn across an irradiation zone vdiilst resting on a thin layer of ice, thence forming a continuous leather - like band. (20)... 

The formation of PAA star polymers using the core first method has been demonstrated in the ATRP process by use of multifunctional initiators [111, 112]. In this method, the number of arms in the star polymer can be determined by the number of initiating sites on the initiator. Star-shaped PtBuA was prepared by the arm first method via ATRP, using divinylbenzene, 1,4-butanediol diacrylate, and EGDMA as coupling reagents [113].

The difunctional monomer methodology has been used for the synthesis of PS ° and poly(tert-butyl acrylate) (PtBuA) star homopolymers.The difunctional monomers used were divinyl benzene and 1,4-butanediol diacrylate,... 

Trumbo and Mote prepared crosslinked networks from TO (Scheme 3.12), via a Diels-Alda- reaction [105], using 1,6-hexanediol- and 1,4-butanediol-diacrylates. They characterized their product and showed that some combinations gave films with 95 per cent of gel fraction. Scheme 3.13 shows the idealized network structure proposed by these authors. The corresponding films had high gloss and good solvent resistance. 

Acrylic acids and methacrylic acids are mostly applied to polymerize monomers. However, esters of their acids are generally used. Monofunctional monomers are basic monomers for photopolymerization and are used for dilution because of low viscosity. Bifunctional monomers induce crosslinking and hard coating. Polymerization of 1,4-butanediol diacrylate (BDDA) is shown below ...
