Abstract. In this paper the conformational characteristics of two
sample (PAA-A- 120 and PAA-A-150) of copolymers ?poly(acrylamide-co-acrylic
acid? were studied by using rectangular pulses. The resulsts of this investigations
shows that these copolymers have the conformational characteristics (great
chains flexibility) enaling their applications in dye and lacquers industry
like water-soluble systems. The investigated copolymers might be an emulgations
or dispersions in the recaptures for dyes and lacquers, since they are
water-soluble, the organic solvents are not present.
ISPITIVANJE KONFORMACIONIH KARAKTERISTIKA
NETOKSIČNIH VODORASTVORNIH KOPOLIMERA
ZA PRIMENU U INDUSTRIJI BOJA I LAKOVA
U ovom radu ispitivane su konformacione karakteristike dva uzorka (PAA-A-120
i PAA-A-150) kopolimera (akrilamid-akrilna kiselina) korišćenjem pravougaonih
električnih impulsa. Rezultati ovih ispitivanja pokazuju da ovi kopolimeri
imaju veliku fleksibilnost lanaca koji omogućavaju njihovu primenu u industriji
boja i lakova u vodorastvornih sistema. Ispitivani kopolimeri mogu biti
emulgujuća tj. disperziona sredstva u recepturi boja i lakova, pa kako
su vodorastvorna time je eliminisano učešće organskih rastvarača.
