Poly(vinyl alcohol)-collagen hydrolysate thermoplastic blends: II. Water penetration and biodegradability of ....
Original language description
Water solubility of polyvinyl alcohol (PVA) is related to degree of hydrolysis, molecular weight and modification during blending in the presence of other processing additives. In the present paper the effect of collagen hydrolysate (CH) and glycerol onPVA water sensitivity has been investigated. CH content affects water penetration into the prepared blown films, affecting therefore their solubility. An increasing content of CH in PVA based blends shortens the time to the first disruption of the filmafter immersing in water, restraining the negative effect of glycerol on solubility. Pure PVA film presented limited biodegradation at low temperature (5 oC). The CH addition in the blend significantly increases biodegradation rate at that temperature. PVA/CH blends properties are of practical relevance for applications as hospital laundry bags and containers of water-soluble substances, such as chemical agents for treatment of waste and potable water, fertilizers, washing agents, sanitary
