Chlorinated isotactic polypropylene (CIPP) with chlorine percentage of 28-35 by weight and random chlorine substitution in polymer has been widely used as adhesives of polypropylene materials (1-5).
To address the difficulty in finding a solvent that is comparable with CTC in terms of inertness to chlorine, cost-effectiveness, and ease of separation, we have tried a solvent that can be chlorinated simultaneously with IPP, forming two useful chlorinated products, i.e., CIPP and chlorinated solvent, in one run.
Later, the reaction temperature was decreased gradually to 70[degrees]C and chlorine gas was continuously fed into the reactor at the said flow rate for 10 h until percentage chlorine of CIPP reached 28-35 by weight.
The chlorine percentage of CIPP and CP are quantitatively determined using the combustion of the product sample, i.e., CIPP or CP.
A high-strength CIPP system developed specifically for pressure water lines has been launched and is being installed successfully."
CIPP Corp., Nate Linder, P.E., staff engineer: "Cured-In-Place Pipe can be manufactured for a number of different pressure pipe applications.
Insituform pressure pipe liner (PPL), the CIPP solution, uses epoxy resin which is NSF approved for potable water.
Additionally, most CIPP materials have proven to frequently be porous and, therefore, not exceptionally good candidates for pressurized pipe applications.
Municipal and industrial customers can rehabilitate deteriorated pipes with a cured-in-place pipe (CIPP) product from National Enviro Tech Group, L.L.C.
Liner Products makes a cured-in-place pipe (CIPP) and has a patented ResinGuard product that protects the saturated inner felt of CIPP systems from squeeze-out and contamination.
