Abstract
Peat moss having increased wettability and increased brightness while maintaining its absorbency and structural integrity is provided. The peat moss is treated so as to chemically graft onto its structure, unhydrolized polymeric chains of the general formula: ##STR1## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and --CH.sub.3, X and Y are selected from the group consisting of --CN, --COONH.sub.2 and --OCH.sub.3 and wherein m and n are integers which when summed together equal at least 500.

Bright, absorbent, highly wettable peat moss having grafted thereon unhydrolyzed polymeric chains of the general formula:
- ##STR4## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and --CH.sub.3, X and Y are selected from the group consisting of --CN, --COOH, --COONH.sub.2, and --OCH.sub.3 ;
- wherein m and n are integers which when summed together equal at least 500;
- said grafted peat having a brightness of more than 80 on the Hunter Scale while still maintaining its capillary structure.
The grafted peat moss of chain 1 wherein said polymeric chains are formed from monomers selected from the group consisting of acrylonitrile, acrylic acid, acrylamide and derivatives and mixtures thereof.
A method of producing bright, absorbent, highly wettable peat moss comprising:
- grafting to peat moss unhydrolyzed polymeric chains of the general formula:
- ##STR5## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and --CH.sub.3, X and Y are selected from the group consisting of --CN, --COOH, --COONH.sub.2, and --OCH.sub.3 ;
- wherein m and n are integers which when summed together equal at least 500, whereby said grafted peat moss has a brightness of more than 80 on the Hunter Scale.
A product for absorbing body fluid comprising as an absorbent element thereof:
- bright, absorbent, highly wettable peat moss having grafted thereon unhydrolyzed polymeric chains of the general formula:
- ##STR6## wherein R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen and --CH.sub.3, X and Y are selected from the group consisting of --CN, --COOH, --COONH.sub.2, and --OCH.sub.3 ;
- wherein m and n are integers which when summed together equal at least 500;
- said grafted peat having a brightness of more than 80 on the Hunter Scale.
