Peel Strength of Al-Plasma Copolymer-PP Systems

In the case of allyl alcohol-ethylene plasma copolymers, the maximum adhesion (650 N m ) was measured at 27-29 OH per 100 C atoms. Therewith, this copolymer exhibits a significantly higher peel strength than the aUyl alcohol homopolymer (85 N m ). Thus, the above ranking of the adhesion-promoting [Pg.277]

COOH groups produce the highest peel strength at A1 (see Fig. 18.7 and Table 18.4). In both cases of deposition of acryhc acid-ethylene or -butadiene [Pg.278]
