High molecular weight methacrylates
WebJan 1, 2014 · From the viewpoints of molecular weight control, a number of effective initiator systems have been intensely developed, as shown in Fig. 3. These initiator systems effectively induce the living anionic polymerization of MMA to give the PMMA predicted molecular weight and narrow molecular weight distributions (M w /M n < 1.1). WebThe invention relates to a thermoplastic composition (P) comprising a copolymer (a) of vinylaromatic monomer and methyl methacrylate monomer, at least two hindered amine light stabilizers, at least two UV absorbers, and optionally further additives. It further relates to a process for the preparation of the thermoplastic composition (P), a process for the …
