摘要: Disclosed is a method for treating a surface of a PVC product. A PVC product including PVC and plasticizer is provided. A surface of the PVC product is treated by an aqueous solution of a crosslinking agent and a first phase transfer catalyst to form a first surface treated PVC product. The surface of the first surface treated PVC product is treated by an aqueous solution of an aqueous free radical initiator and a second phase transfer catalyst to form a second surface treated PVC product. As such, the release of the plasticizer from the PVC product to an environment is inhibited.

摘要: Disclosed is an amorphous copolyester polymerized of a diacid and diols. The diacid is selected from a group consisting of terephthalic acid, 5-tert-butylisophthalic acid, and dimethyl 2,6-naphthalenedicarboxylate. The diols are selected at least two from a group consisting of ethylene glycol, 2,2-dimethyl-1,3-propanediol, and tricyclodecanedimethanol. The molar ratio of the tricyclodecanedimethanol is 30% to 95% of the diols.
