A novel copolymer network with acetal structure was prepared using bis [4-(vinyloxy)butyl] (4-methyl-1,3-phenylene)biscarbamate (BECT) as the crosslinking agent. Firstly, a tri-copolymer of maleic anhydride (MAn), n-butyl vinyl ether (BVE) and 4-hydroxybutyl vinyl ether (HBVE) was synthesized via free-radical polymerization with 2,2′-azobisisobutyronitrile as the initiator. The tri-copolymer consisted of two sorts of alternating units, MAn-alt-BVE and MAn-alt-HBVE. The linear copolymer Poly((MAn-alt-BVE)-co-(MAn-alt-HBVE)) with pending hydroxyl groups was then combined with BECT in the presence of pyridinium p-toluenesulfonate, generating a copolymer network comprising acetal components in the crosslinking segment. This polymer network exhibited degradation in acid conditions.

The strong‐base catalyzed addition of acetylene to form a variety of vinylic compounds is generally referred to as the Reppe vinylation or Reppe synthesis. It has been suggested that acetylene can be handled safely under these reaction conditions being an explosive substance. The study finds the option of dilution with inert nitrogen is good for an autoclave operation, whereas the condition with minimized free space is good for continuous operation, especially with solid contact catalyst. Several reactions have been discussed using catalysts, such as KOH, zinc, cadmium acetates, and zinc naphthenate. This reaction has very important industrial applications for the production of vinylic monomers for polymerization.
