TīmeklisPolyvinylacetate (PVAC, PVA) Properties and Applications. Polyvinyl acetate (PVAc, PVA) is an atactic, highly branched, and noncrystalline thermoplastic, prepared by conventional free-radical polymerization.It has good resistance to UV and oxidation, but is rather brittle below its Tg (ca. 35°C) and very sticky above it. TīmeklisThe retina can be affected by many conditions that damage your eye. Conditions that specifically affect the retina include: Age-related macular degeneration. Macular hole. Macular pucker. Retinal vein occlusion or retinal artery occlusion. Retinal detachment. Eye floaters and flashes and posterior vitreous detachment.
