Patent ID: 7276282

Claim:
A reinforcement yarn coated with a sizing composition comprising at least one silane satisfying the following formula: Si(R 1 )(R 2 )(R 3 )(R 4 ) wherein: R 1 and R 2 are identical or different, and are selected from the group consisting of: —H, —Cl, —O—R 5 , —O—R 6 —O—R 5 , —O—(C═O)—R 5 , and —O—R 6 —(C═O)—R 5 ; R 3 is selected from the group consisting of: Cl, —O—R 5 , —O—R 6 —O—R 5 , —O—(C═O)—R 5 , and —O—R 6 —(C═O)—R 5 ; R 5 and R 6 are derived from identical or different hydrocarbons, and are selected from hydrocarbon radicals having from 1 to 4 carbon atoms in the main chain; R 4 ═—R 7 —NHR 8 ; R 7 is selected from branched hydrocarbon radicals having from 2 to 6 carbon atoms in the main chain; R 8 is selected from the group consisting of: —H, —R 9 —NH 2 , and —R 10 —NH—R 9 —NH 2 ; R 9 is selected from hydrocarbon radicals comprising from 1 to 12 carbon atoms or from carbonyls; and R 10 is selected from hydrocarbon radicals having from 1 to 6 carbon atoms in the main chain.
