English term or phrase: monomer component
The cement is packaged in two sterile components; a liquid monomer component and a
powder copolymer component.

Selected answer:monomer component
Explanation:
Apparently the cement is made by mixing together two components - an inert powder and a monomer liquid. The fact that the powder happens to be a copolymer is beside the point, its only role is to form an easily handled dough-like mass when mixed with the liquid. Apparently it may also contain antibiotics or other medication.

The liquid component is a monomer, small molecules that together form a large solid three-dimensional polymer structure in the polymerization reaction. The powder particles of the other component are mechanically locked in this structure, forming a sort of a composite material.

I don't know what exactly initiates the reaction, often it initiated by light.

"The cement is packaged in two sterile components" should be "The cement is packaged AS two sterile components" or "supplied in the form of two components in separate sterile packaging".

the mollecule of a certain substance that will form a polymer


Explanation:
In chemistry, a monomer (from Greek mono "one" and meros "part") is a small molecule that may become chemically bonded to other monomers to form a polymer.
http://en.wikipedia.org/wiki/Monomer

so in the case of cement:
The liquid monomer component is comprised of methyl
methacrylate, N.N-dimethyl-p-toluidine, and hydroquinone.
the powder copolymer component is made of: Erythromycin (as glucoheptonate USP) 500 mg
Colistin sulphomethate sodium EP

part of the cement containing the basic synthetic unit of polymorization


Explanation:
"Component" (as a general term) refers to a reacting species in cement composition, I think.

Definition from wikipedia:
http://en.wikipedia.org/wiki/Monomer

In chemistry, a monomer (from Greek mono "one" and meros "part") is a small molecule that may become chemically bonded to other monomers to form a polymer.

simple chemical compound of low molecular weight that can be polymerized


Explanation:
a molecule of any of a class of compounds, mostly organic, that can react with other molecules of the same or other compound to form very large molecules, or polymers. The essential feature of a monomer is polyfunctionality, the capacity to form chemical bonds to at least two other monomer molecules

monomer component
a part constructed of a monomer material


Explanation:
packaging part made of liquid monomer material

A monomer is a type of polymer where one molecular unit, by repetition, consistute a large structure. For example polyethylene is made of repetitive units of ethylene.

On the other hand, a copolymer is a polymer where two or more molecular units are combined.

I need to add that what I really think here is that in this case the monomer may be a typo for monopolymer, as opposed to copolymer. A monomer is a unit and not the compound itself.

neutral  Jörgen Slet: not a "part constructed of a monomer" but the starting material of a polymer
7 hrs
  -> the "monomer component" is a "part constructed of a monomer" or rather a monopolymer, based on my last note.
