Abstract

The grafting of methacrylic acid to nylon by the preirradiation technique has been studied. The rate of grafting is appreciably larger than that of homopolymerization. No simple relation exists between reaction rate and total dose. The temperature dependence of the rate of grafting to the fibre, preirradiated in air, indicates that initiation of grafting is likely to take place by decomposition of peroxide groups formed on irradiation. Electrical resistance measurements on the irradiated fibre indicate that this has been reduced by a factor of 10.

La vitesse du greffage est sensiblement plus grande que celle de l'homopolymerisation. Il n'existe pas de rapport simple entre la vitesse de reaction et la dose totale. Le fait que la vitesse du greffage sur la fibre, pre-irradiee a l'air, depend de la temperature, indique que l'amorcage de la greffe est susceptible d'etre provoque par la decomposition des groupements de peroxyde formes lors de l'irradiation.

No existe una relacion sencilla entre la velocidad de reaccion y la dosis total. La influencia de la temperatura sobre la velocidad de injerto en la fibra previamente irradiada en aire indica que el proceso se inicia por descomposicion de los grupos peroxido formados durante la irradiacion. Las mediciones efectuadas demuestran que la resistencia electrica de la fibra irradiada solo alcanza la decima parte de la correspondiente a la fibra no tratada.

Skorost' prosachivaniya otnositel'no bol'she, chem skorost' komopolimerizatsii. Ne sushchestvuet prostoj svyazi mezhdu skorost'yu reaktsii i vsej dozoj. Temperaturnaya zavisimost' skorosti prosachivaniya v volokno, podgotovlennoe k oblucheniyu v vozdukhe, ukazyvaet, chto nachalo prosachivaniya, po-vidimomu, proiskhodit putem razlozheniya peroksidnykh grupp, obrazovannykh posle oblucheniya.
