TITLE 21--FOOD AND DRUGS
CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
SERVICES (CONTINUED)
PART 177 INDIRECT FOOD ADDITIVES: POLYMERS--Table of Contents
Subpart B Substances for Use as Basic Components of Single and Repeated
Use Food Contact Surfaces
Sec. 177.1060 n-Alkylglutarimide/acrylic copolymers.
n-Alkylglutarimide/acrylic copolymers identified in this section may
be safely used as articles or components of articles intended for use in
contact with food subject to provisions of this section and part 174 of
this chapter.
(a) Identity. For the purpose of this section, n-alkylglutarimide/
acrylic copolymers are copolymers obtained by reaction of substances
permitted by Sec. 177.1010(a) (1), (2), and (3) with the following
substance: Monomethylamine (CAS Reg. No. 74-89-5), to form n-
methylglutarimide/acrylic copolymers.
(b) Adjuvants. The copolymers identified in paragraph (a) of this
section may contain adjuvant substances required in their production.
The optional adjuvant substances required in the production of the basic
polymer may include substances permitted for such use by applicable
regulations, as set forth in part 174 of this chapter.
(c) Specifications. Maximum nitrogen content of the copolymer
determined by micro-Kjeldahl analysis, shall not exceed 8 percent.
(d) Limitations. (1) The n-alkyl glutar imide/acrylic copolymers in
the finished form in which they shall contact food, when extracted with
the solvent or solvents characterizing the type of food and under the
conditions of time and temperature described in tables 1 and 2 of Sec.
176.170(c) of this chapter, shall yield extractives not to exceed the
limitations of Sec. 177.1010(b) of this chapter, when prepared as
strips, as described in Sec. 177.1010(c)(2) of this chapter.
(2) The n-alkylglutarimide/acrylic copolymers shall not be used as
polymer modifiers in vinyl chloride homo- or copolymers.
(e) Conditions of use. The n-alkylglutarimide/acrylic copolymers are
used as articles or components of articles (other than articles composed
of vinyl chloride homo- or copolymers) intended for use in contact with
all foods except beverages containing more than 8 percent alcohol under
conditions of use D, E, F, and G as described in table 2 of Sec.
176.170(c) of this chapter.
