1. A process for producing a polymer, said process comprising the step: polymerizing at least one ethylenically unsaturated monomer in the presence of a catalyst and a liquid carrier, wherein said liquid carrier is a reactive diluent that is substantially non-reacting with said at least one ethylenically unsaturated monomer and components of said polymer during said process, said reactive diluent having at least two reactive sites, wherein said reactive diluent is selected from the group consisting of amide acetal, ketimine, cyclic carbonate, orthoester, spiro-orthoester, bicyclic orthocarbonate, and a combination thereof.
2. The process of claim 1 wherein the reactive diluent is an amide acetal.
3. The process of claim 1 wherein said polymer is selected from the group consisting of (meth)acrylic polymer and styrenated (meth)acrylic polymer.
4. The process of claim 3 wherein said polymer contains at least one crosslinkable functional group.
5. The process of claim 1 wherein the polymerization is performed at a temperature sufficient to polymerize the ethylenically unsaturated monomer.
6. A composition obtained by the process of claim 3 and further comprising a crosslinking agent.
7. A composition comprising;
(a) at least one ethylenically unsaturated monomer;
(b) at least one reactive diluent that is substantially non-reacting with said at least one ethylenically unsaturated monomer; and
(c) at least one catalyst suitable to catalyze the polymerization of said ethylenically unsaturated monomer in a process to form a polymer;
wherein said reactive diluent is selected from the group consisting of amide acetals, ketimines, cyclic carbonates, orthoesters, spiro-orthoesters, bicyclic orthocarbonates, and a combination thereof, and said reactive diluent is substantially non-reacting with components of said polymer during said process.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A nozzle box assembly comprising:
a torus having a plurality of steam inlets and an annular steam outlet;
a steam path ring having an annular steam inlet, said annular steam inlet having an inner diameter (ID) and an outer diameter (OD), said steam path ring disposed downstream of said torus; and,
a bridge ring having an annular steam inlet and an annular steam outlet, said annular steam outlet having an ID and an OD, said bridge ring disposed between said torus and said steam path ring, said bridge ring annular steam outlet is adjacent to said steam path ring annular steam inlet, wherein said steam path ring annular steam inlet OD is greater than said bridge ring annular steam outlet OD and said steam path ring annular steam inlet ID is smaller than said bridge ring annular steam outlet ID.
2. The nozzle box assembly of claim 1 wherein the difference between said steam path ring and said bridge ring OD’s and ID’s form a radial step.
3. The nozzle box assembly of claim 2 wherein said radial step is between about 0.000 in. and about 0.060 in.

6. A method for directing steam flow through a nozzle box assembly comprising:
conveying a steam flow through a torus; and,
directing the steam flow downstream of said torus over a radially outward step at an interface between a bridge ring and a steam path ring.
7. A steam path ring comprising:
a series of nozzles directing steam flow; and,
an annular steam inlet, said annular steam inlet having an inner diameter (ID) and an outer diameter (OD), wherein said steam path ring annular steam inlet ID is smaller than a bridge ring annular steam outlet ID and said steam path ring annular steam inlet OD is greater than a bridge ring annular steam outlet OD.
8. The steam path ring of claim 7 wherein the difference between said steam path ring and said bridge ring OD’s and ID’s form a radial step.
9. The steam path ring of claim 7 wherein said radial step is between about 0.000 in. and about 0.060 in.
