| Abstract [eng] |
In order to improve the ageing resistance of adhesive films used as a support for museum textiles, the units of vinyl acetate in an adhesive copolymer were replaced by the units ofvinyl neodecanoate 10 (VeoVa). Several VeoVa terpolymers and tetrapolymers with various (meth)acrylates were synthesized and studied. The composition of the new copolymers was calculated referring to both acid value and integral signals in 'H-NMR spectra. The coating features of the new adhesives on a supporting silk fabric were evaluated. It was determined that the tetrapolymers containing about 15 mol.% of VeoVa units, 5 mol.% of AA units and the right ratio of the units of MMA and BA met the requirements for textile adhesives. Changes m the chemical stmcture of the copolymers under artificial ageing were assessed by ATR-FTIR spectroscopy, including difference spectra obtained by subtracting the spectrum of a control sample from the spectrum of the artificially aged samples. The spectral data revealed autooxidative processes takmg place under ageing, leading to rupture of the lateral VeoVa groups in the initial stage of the process and a cleavage of the polymer main chain under a prolonged artificial ageing of the adhesive layers. |
