This process results in an improved thermal stability of the gratings [31]. Another example relates to the photo-cross-linking of a copolymer of the structure shov n in Chart 7.5 [32]. 

The occurrence of these reactions is restricted to the amorphous phase. Therefore, the photo-cross-linking process has to be performed at temperatures exceeding the crystalline melting point in the case of highly crystalline polymers such as polyethylene. The cross-linking efficiency can be strongly enhanced by the addition of small amounts of multifunctional compounds such as triallyl cyanurate, TAG (see Chart 7.9), or by the incorporation of special diene moieties into copolymers such as ethylene propylene diene copolymers (EPDM elastomers) [33].

Systematic studies on photo-cross-linking block copolymer micelles, with a core of poly(cinnamoylethyl methacrylate) (PCEMA) were published by Liu and co-workers [229]. With PAA as the shell-forming block, these authors could demonstrate by SLS, DLS, TEM and SEC that photo-cross-linking of PCEMA locked in the initial structure of the micelles without any significant change in their aggregation number and size distribution. Corecross-linking of PEO-PMAA micellar systems with Ca ions has recently been described by Kabanov and co-workers [230].
