Synthesis and properties of graft copolymer of cellulose diacetate with poly(caprolactone monoacrylate)

Abstract

Cellulose diacetate grafting poly(caprolactone monoacrylate) copolymers (CDA-g-PCLA) were synthesized by a two-step reaction of cellulose diacetate (CDA) with poly(caprolactone monoacrylate) (PCLA). The isocyanate-terminated intermediate (NCOPCLA) was prepared and grafted onto cellulose diacetate chains. The results of the structure analysis indicated that PCLA was connected to CDA by chemical bonding. The flow temperature of graft copolymers was lower than that of the pure CDA and decreased with increasing the grafting percentage. Outdoor soil burial tests and active sludge tests indicated that the graft copolymers have good biodegradability in natural conditions.

Synthesis of graft copolymer of ethyl cellulose through living polymerization and its self-assembly

“…In most cases, the concurrent formation of homopolymers and copolymers predominates over graft copolymerization. Grafting of vinyl monomers from the mixture of synthetic and natural polymers, being very important since the chains with desired composition and length can be introduced by manipulating the grafting conditions and selecting monomers of desired properties, has been reported rarely (Daly et al 2001;Yue and Cowie 2002;Wang et al 2003;Takolpuckdee et al 2004).…”

The Synthesis of Cellulose-graft-poly (L-lactide) by Ring-opening Polymerization and the Study of Its Degradability

“…[1][2][3][4] As the most abundant renewable natural biomass, cellulose offered a favourable combination of low cost, biodegradation, the ease of fiber surface modification, good mechanical properties, low density, and recyclability comparing with its inorganic counterparts. 5,6 However, there were also some challenges to the chemical modification of cellulose because of its high molecular weight, high crystallinity, rigidity of backbone chain and insolubility.…”

Cellulose Diacetate-g-poly(p-dioxanone) Co-polymer: Synthesis, Properties and Microsphere Preparation

“…In contrast to the case for natural cellulose, CA not only keeps some original properties of polysaccharide but also shows the relatively good solubility in some solvents and thermoplastic property [24]. Some investigations on the graft co-polymerization between aliphatic polyester and CA have been reported excessively [25][26][27][28][29][30]. For example, Teramoto et al accomplished the graft co-polymerization of ε-caprolactone (CL) and lactic acid (LA) onto cellulose diacetate [27].…”
