Substituents are given before the name of the diradical. Poly(vinyl alcohol) is thus correctly called poly(hydroxyethylene) (Example 9) and poly(methyl methacrylate) is called, according to lUPAC, poly[(l-meth-oxycarbonyl)- -methyl ethylene] (Example 10). 

Substituents are generally given before the name of the diradical. Poly(vinyl alcohol) (example 4, Table 1-4) is thus correctly called poly-(hydroxyethylene). Another example is poly(l-oxotrimethylene) (example 11, Table 1-4). Note that the name of the diradical is always given in parentheses or other brackets. All examples given in Table 1-4 have structural names which imply a direction in the polymer chain. This direction is not always the same as the direction of chain propagation in polyreactions (see examples 5,6, and 9 in Table 1-4).

The lUPAC systematic name for poly(vinyl acetate) is poly-(l-acetoxy-ethylene) and that for poly(vinyl alcohol) is poly-(l-hydroxyethylene). As with other common polymers the lUPAC names are not in general use. 

By utilizing a combination of RAFT and cationic ROP, the synthesis of [poly(methyl methacrylate)][poly(l,3-dioxepane)][polystyrene] miktoarm star terpolymers was achieved [182], The approach involved the synthesis of PS functionalized with a dithiobenzoate group by RAFT polymerization and subsequent reaction with hydroxyethylene cinnamate (Scheme 98). The newly created hydroxyl group was then used for the cationic ring opening polymerization of 1,3-dioxepane (DOP). The remaining dithiobenzoate group was used for the RAFT polymerization of methyl methacrylate.

Aral and Ise carried out the hydrolysis of dextrin in the presence of copolymers of vinyl alcohol and vinylsulfonic aethylenesulfonic acid unit relative to sulfuric add, Acopoiymet/ H2S04> increased from 1 to 1.4 at 80 °C, as the mole ratio of hydroxyethylene and ethylenesulfonic add repeat units wsB varied from nearly zero to 100. On the other hand, mixtures of pofy(ethylenesul-fonic add) 3 and poly(vinyl alcohol) possessed a catalytic efficiency lower than that of sulfuric add.

Poly(styrene-co-vinyl alcohol) n. Poly (ethenyl benzene -co- 1 hydroxyethylene). 

It is a unique polymer as even in its atactic form that lacks stereoregularity, it exhibits semicrystallinity. Other interesting synthetic hydrogels are made by poly(2-hydroxyethylene methacrylate), poly(A -isopropylacrylamide), and poly(glycerol seba-cate), an elastomeric polymer with strong mechanical properties, biodegradability, and good biocompatibility (Radhakrishnan, 2014).
