I‰vados·iame darbe i‰tirti akriliniai polimerai – Paraloid B-72, Paraloid B-82 ir PlexisolP550-40 tinka modernios aliejinòs tapybos restauravimui. Tyrimais nustatyta, kadjie sendami yra pakankamai chemi‰kai stabilapples, nerappleg‰tòja ir nekeiãia spalvos, juosnesudòtinga pa‰alinti nuo tapybos pavir‰iaus po suklijavimo.Vilgymo kampo ir adhezijos tyrimais nustatyta, kad tirt˜j˜ polimer˜ sklidimas iradhezija ant aliejini˜ pavir‰i˜ labiausiai priklauso nuo panaudot˜ tirpikli˜.Tvirtinant plonà, poròtà, matin∞ daϘ sluoksn∞, rekomenduojama naudoti PlexisolP550-40 tirpalus vaitspirite, nes jo dangos nòra blizgios.Tvirtinant storà, faktapplerin∞, daϘ sluoksn∞, reikia rinktis polimer˜ tirpalus, kuriepasiÏymi geresniu vilgymu ir stipresne adhezija, tokius, kaip Paraloid B-72 ir ParaloidB-82 tolueno ir izopropilo alkoholio mi‰iniuose.Literatra1.

Properties and ageing of three acrylic polymersParaloid B-72, Paraloid B-82, Plexisol P550 have been studied in connection withthe use of these polymers in the conservation of modern paintings. Change ofcolor, brightness, wetting angle, adhesion and reversibility of consolidation processwere researched. The obtained data was used to assess the stability, changesand compatibility of polymers with painting materials. The results revealed that allthree polymers were conveyable for this task, the solvent used together was moreimportant.T YRINñ JIMAI / 41
