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-alkylglutarimide/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.
