Poly styrene n

Six arm star polystyrenes were prepared by the core-first method using initiator 13 with six phenylethylchloride-type functions emanating from a central hexa-substituted benzene ring [24].

With poly (methylene), the number of chain units N is identical to the degree of polymerization Xn. However, for monomeric units of two units, e.g., poly(styrene), N= 2Xn. The relation between the radius of gyration and the chain end-to-end distance is then... 

The diffusion and reaction of amino-telechelic polybutadiene in poly(styrene-n-butyl acrylate/ TMI)(PSBT) was studied. Amonodisperse seed latex was prepared by semicontinuous emulsion polymerisation. Two core-shell latices were also prepared semicontinuously, using the seed latex as the core and poly(styrene-n-butyl acrylate) as the shell. These monodisperse latices were mixed with equivalent amounts of the amino-telechelic polybutadiene artificial latex before casting into films. Consumption of the TMI (dimethyl meta-isopropenyl benzyl isocyanate) in these films was monitored by FTIR as a function of time and the amino/TMI ratio. 6 refs.

Table 1. Second virial coefficient of poly(styrene-n//-benzyl methacrylate).

Graft copolymers of polychloroprene and a cationic starch imparted wet-strength properties to paper when applied as wet-end additives to pulp, and they also exhibited cold-contact adhesive properties without pressure being applied. Poly(styrene-n//-acrylonitrile) has been grafted onto starch. ...
