Abstract
Hydrolyzable film- and fiber-forming polymers having a plurality of repeating units of the formula: ##STR1## wherein R is lower alkyl, aryl, alkaryl and aralkyl; R 1 , R 2 and R 3 are each selected from H or lower alkyl with the proviso that at least one of R 1 , R 2 , R 3 is H; and n is an integer of 0 to 2.
Claims
exact text as granted — not AI-modifiedWhat is claimed is: .[.1. A hydrolyzable film- and fiber-forming polymer having a plurality of repeating units of the formula: ##STR9## wherein R is lower alkyl, aryl, alkaryl, or aralkyl; R 1 , R 2 and R 3 are each selected from H or lower alkyl with the proviso that at least one of R 1 , R 2 and R 3 is H; and n is an integer of 0
to 2..]. .[.2. A film- and fiber-forming polymer of claim 1 wherein R is lower alkyl..]. .[.3. film- and fiber-forming polymer of claim 2 wherein the lower alkyl is methyl..]. .[.4. A film- and fiber-forming polymer of claim 1 wherein the R is aralkyl..]. .[.5. A film- and fiber-forming polymer of claim 1 wherein the aralkyl is benzyl..]. .[.6.
