I think they basically tried that... and I thought it was a good idea... but I don't think that worked so well the way they tried it.
Since a copolymer consists of at least two types of constituent units (also structural units), copolymers can be classified based on how these units are arranged along the chain. These include:
Alternating copolymers with regular alternating A and B units (2)
Periodic copolymers with A and B units arranged in a repeating sequence (e.g. (A-B-A-B-B-A-A-A-A-B-B-B)n)
Statistical Copolymers are copolymers in which the sequence of monomer residues follows a statistical rule. If the probability of finding a given type monomer residue at a particular point in the chain is equal to the mole fraction of that monomer residue in the chain, then the polymer may be referred to as a truly random copolymer (3).
Block copolymers comprise two or more homopolymer subunits linked by covalent bonds (4). The union of the homopolymer subunits may require an intermediate non-repeating subunit, known as a junction block. Block copolymers with two or three distinct blocks are called diblock copolymers and triblock copolymers, respectively.
Copolymers may also be described in terms of the existence of or arrangement of branches in the polymer structure. Linear copolymers consist of a single main chain whereas branched copolymers consist of a single main chain with one or more polymeric side chains.
Other special types of branched copolymers include star copolymers, brush copolymers, and comb copolymers.
A terpolymer is a copolymer consisting of three distinct monomers. The term is derived from ter (Latin), meaning thrice, and polymer.

I just gotta point this out- EVERYONE'S been whinging on and crying about BP and the oil spill- but not a frigging one of them has shown up to offer a concrete, workable solution, or any solution at all.
Verry Interesting, yes- no?

Lemme give this some thought (and Like us all, I need to THINK FAST)
I was (not nicely) thinking about shoving the CEO's butt into the pipe- and it occurred to me- Is there not a compound that can be made or had that acts like expanding foam (like Great stuff)- that would react ONLY to oil- turning it into an inert mass, and basically stopping up the pipe like cholesterol would clog an artery? It'd have to be waterproof- and have to be injected, or even just left at the base of the pipe, so it flows INTO the oil stream.... I know they have something like this for water- it's a powder that turns water into a gel- they use it for both cleanups and for magic tricks. Heck, Why not get a LOT of that, and use it as a temp barrier/ way to cleanup some of it.
I'll check back tomorrow when I am somewhat more coherent. And awake.
Edit: I lied a bit about going to bed. Here's what I was talking about: Water gel
I need to go to bed- I had a thought... "just wrap a giant diaper with this stuff in it"... Yeah. Okie day. Instead of a 'giant diaper', how about a giant mesh with this stuff encapsulated and set as a time release, in a 'nested ball' way- the first layer closest to the pipe blows a large amount of this or a similar compound out, followed by successive ones, and a hose is dangled to the center of the ball with a plug on it (keeping water out til it's all in position) in the ball, and it pumps it in as these successive releases happen... If no one's laughing at this idea tomorrow, I might do a graphic, too.
