preparation example Construction
[0114] The preparation of polyvinyl acetal (PVA) is well known in the art. For example, PVA can be prepared from aldehydes and polyvinyl alcohol. Acetals are formed by the well-known reaction between aldehydes and alcohols. Addition of an alcohol molecule from an aldehyde molecule produces a hemiacetal. Hemiacetals are rarely isolated because of their inherent instability, but, in fact, further react with another alcohol molecule to form a stable acetal.
[0115] Polyvinyl alcohol is a high molecular weight resin containing varying proportions of hydroxyl and acetate groups produced by the hydrolysis of polyvinyl acetate. The conditions of the acetalization reaction and the concentrations of the particular aldehyde and polyvinyl alcohol used are closely controlled to form a polymer containing predetermined proportions of hydroxyl, acetate and acetal groups. The final product can be represented by the following formatted structure. The proportions of A, B and C are controll...
Embodiment 1
[0202] Embodiment 1. Antibacterial sealant
[0203] This embodiment provides an antimicrobial sealant (or antimicrobial sealant) that can be used, for example, to minimize surgical site infections.
[0204] According to the CDC, nearly half a million surgical site infections (SSIs) occur each year in the United States, making them the second most common health care-associated infection. In clean surgery, direct inoculation of the patient's own skin mass is a major source of incision contamination. Due to the incomplete disinfection of the skin and the rebound growth of bacteria in the deep layer of the skin during the operation. There are two ways to minimize SSI, maintaining normal body temperature and using microbial sealants.
[0205] In this example, 1.0 grams of PVB [Solutia, Inc. (Solutia Corporation) B76, ] was transferred to a flask (250 ml) and filled with 200°C (proof) absolute ethanol (100 ml). The mixture was stirred for 5 hours to dissolve all PVB particle...
Embodiment 1A
[0208] Example 1A. Antibacterial sealant
[0209] In this example, 1.0 grams of PVB [Solutia, Inc. (Solutia Corporation) B76, ] was transferred to a flask (250ml) and filled with methyl acetate (100ml). The mixture was stirred for 5 hours to dissolve all PVB particles. Then 30 mg of (3-glycidyloxypropyl)pentamethyldisiloxane was added to the above solvent and the whole mixture was further stirred for 30 minutes.
