The cloud temperature of the at least one nonionic surfactant is preferably less than the polymerization temperature.

The temperature in the remaining areas of the preform body (1) is lower than the polymerisation temperature (Tpoly).

The temperature at which the process is carried out is preferably at least 20 °C greater than the polymerisation temperature.

Increase in polymerization temperature produces decrease in MI; whereas, decrease in polymerization temperature produces increase in MI.

The polymerization temperature is preferably determined and set by the pressure prevailing in the system.

The fibers comprise fibers (21) with a melting temperature below the curing temperature.

An increase in the polymerization temperature leads to a decrease in the copolymer stress exponent, and vice versa.

High curing temperature and humidity significantly accelerate the strength gains.

Multiple plates can be arrayed to form multiple chambers, and each chamber’s polymerization temperature, as well as resident polymerization mixture, can be individually predetermined.

The fibers comprise fibers (20) with a melting temperature above the curing temperature of the binder.

The balance of the polymerization temperature, α,β-unsaturated carboxylic acid concentration, and cross-linking agent concentration during polymerization is adjusted to achieve the abovementioned viscosity.

In accordance with the present invention, an acrylic ester polymer syrup can be obtained with a degree of polymerization of 20 to 70 % at a low polymerization temperature, even with a small amount of initiator.

The boiling point of the nonaqueous solvent is greater than a temperature at which the polymeric precursor may be mixed and below a temperature at which the polymeric precursor polymerizes or decomposes.

Next, the damp fiber is cut or chopped and heated to the green-state cure temperature of the resin.

A first heat treatment is then performed on the garment, at a temperature less than the polymerising temperature of the above resin, until the garment dries.
