1. 1. Synthesis and characterization of a greener poly(vinyl acetate) adhesive

   University essay from KTH/Fiber- och polymerteknologi

   Author : Xiuting Zhang; [2023]
   Keywords : poly vinyl acetate -grafted-chitosan; chitosan; poly vinyl acetate ; ceric ammonium nitrate; green adhesive; poly vinyl acetat -ympad kitosan; poly vinyl acetat ; ceriumammoniumnitrat CAN ; grönt lim;

   Abstract : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. READ MORE

3. 2. A Comparative Life Cycle Assessment of Alternative Polymers to Poly(vinyl chloride) for Use in Flooring Applications

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Caroline Almqvist; Pernilla Larsson; [2021]
   Keywords : PVC; Flooring; Life Cycle Assessment; LCA; Polymer technology; Earth and Environmental Sciences; Chemistry; Technology and Engineering;

   Abstract : Poly(vinyl chloride) has a long history of use in the flooring industry. Throughout the years, several environmental and health issues have arisen concerning the production, usage and disposal of PVC. READ MORE

4. 3. Reaction Mechanism between Chitosan and Cerium(VI) Ammonium Nitrate for Production of a Greener Poly(Vinyl Acetate) Adhesive

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Mårten Schollin; [2021]
   Keywords : Chitosan; Poly vinyl acetate ; Cerium IV ammonium nitrate ; Grafting; Reaction mechanism;

   Abstract : Poly(vinyl acetate) (PVAc) has a major application as an indoor wood adhesive. Low water stability is however, one of the greatest drawbacks of PVAc. By grafting PVAc from a chitosan (CS) backbone (CS-graft- PVAc) water stability of adhesive is increased while good mechanical and adhesive properties are retained. READ MORE

5. 4. Glucose Levulinates as Bio-plasticizers

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Wenxiang Xuan; [2017]
   Keywords : Gluocse esters; Levulinic acid; Plasticizer; Starch; Poly vinyl chloride ;

   Abstract : Glucose, as the most plentiful sugar in nature, is a renewable resource and possesses excellent record in health safety. Levulinic acid is a platform chemical which plays an important role  in  biomass transformation and reactive intermediates. READ MORE

6. 5. Emulsion polymerization of vinyl acetate with renewable raw materials as protective colloids

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Hanna Lange; [2011]
   Keywords : Poly vinyl alcohol PVA ; Hydroxyethyl cellulose HEC ; Emulsion polymerization; Protective colloid; Starch;

   Abstract : Emulsion polymerizations of vinyl acetate (VAc) were performed by fully or partially replacing poly(vinyl alcohol) (PVA) with renewable materials as protective colloids or by adding renewable materials, as additives or fillers, to the emulsions during or after polymerization. The purpose of the study was to increase the amount of renewable materials in the emulsion. READ MORE
