Methyl Methacrylate → HCID 168661, compound

Participants

Reaction Steps

20 Parts of the first copolymer, 6 parts of a Fischer-Tropsch wax formed from natural gas (trade name: FT-100, supplied by Shell MDS (Malaysia) Sdn. Bhd.) and 100 parts of xylene were placed in a flask and dissolved. The inner atmosphere of the flask was replaced with nitrogen gas, and the mixture was heated up to the boiling point of xylene. While the mixture was stirred under the reflux of xylene, a mixture containing 77 parts of styrene, 3 parts of methyl methacrylate, 14 parts of n-butyl acrylate and 3.5 parts of benzoyl peroxide (polymerization initiator) were dropwise added over 2 hours to carry out a solution polymerization. After the addition was completed, the reaction mixture was aged for 1 hour with stirring under the reflux of xylene, to give a styrene/methyl methacrylate/n-butyl acrylate (to be sometimes referred to as styrene/MMA/BA hereinafter) copolymer.
