    摘要: This invention relates to liners containing contaminants, such as styrene, and to methods for lining pipes, such as sewer pipes with liners containing contaminants, such as styrene. In one embodiment, this invention provides a liner and lining method that reduces contamination of the ambient with contaminants from the liner and/or the lining process, such as styrene. In the case of sewers, the carrier pipes lined may be, for example, PVC, clay or concrete, but pipes of metal or other materials, such as asbestos, may also be lined with the liner and lining method of this invention.
