Organosilane compounds and methods of making and using the same

A method of coating a matrix reinforcement material, the method comprising:

• providing a matrix reinforcement material and a sizing composition comprising a compound of formula (I):
• wherein:
• G1 is —(CH2)9-, —(CH2)IO—, or —(CH2)n-;
• G2 is —CH2- or C(O);
• R1 is an organosilane moiety;
• R2 is —O—R3, —NH—R4, or —N(R6)(R7);
• R3, R4, R6, and R7 are independently C1-12 alkyl, C2-12 alkenyl, or Ci-101 heteroalkyl, each of which is optionally substituted one or more times by substituents selected independently from Rx, and
• Rx is a halogen atom, —OH, —NH2, C1-6 alkyl, C2-6 alkenyl, C1-12 heteroalkyl, or Ce-14 aryl, wherein any two —OH substituents on immediately adjacent carbon atoms may optionally combine to form an epoxy group, and wherein R6 and R7 may optionally combine to form a nitrogen-containing ring;
• and
• contacting the matrix reinforcement material with the sizing composition.
