摘要 |
<p>Plastic sheet which contains a copolyester which copolyester contains 45-50 mole % monomer units derived from a first aliphatic diol, 45-50 mole % monomer units derived from a first aromatic dicarboxylic acid and 0.5-5 mole % monomer units derived from a second aliphatic diol and/or a second aromatic dicarboxylic acid, with the plastic sheet comprising a core section which contains the copolyester and there being present on at least one surface of the sheet a surface layer of thickness 2-100 mu which contains the copolyester and 1-15 wt.% of a UV light-absorbing additive, with the exception of plastic sheets whose core section and surface layer contain a copolyester that contains 50 mole % monomer units derived from terephthalic acid, 49.5-45 mole % monomer units derived from ethylene glycol and 0.5-5 mole % monomer units derived from cyclohexane dimethanol. The plastic sheet has a lower rate of crystallization, better surface quality and better resistance to solvents.</p> |
