## Abstract Poly(methyl methacrylate‐__ran__‐styrene) copolymers were synthesized under monomer‐starved conditions by emulsion copolymerization. The glass‐transition temperatures (__T__~__g__~'s) of the copolymers were measured by differential scanning calorimetry (DSC) and torsional braid analysis
## Abstract Poly(MMA‐__ran__‐St) samples were synthesized under monomer‐starved conditions (drop feeding method) by emulsion copolymerization. Their thermostability was determined by thermogravimetric analysis. The glass transition temperature (__T__~g~) of the copolymers was determined by differen
Two series of (styrene)-(methyl methacrylate) of copolymers were used for determination of the glass transition temperature (Tg), applying DTA and chromatographic measurements. The influence of average molecular weight on Tg was investigated for the first series and the influence of copolymer compos
