Abstract

The production of biobased copolymers such as poly(styrene-co-butyl acrylate-co-methacrylic acid) for paints and coating applications is indispensable for the establishment of sustainable biorefine...

Highlights

The copolymers of styrene (St) and n-butyl acrylate (BA) are important polymeric materials commercially utilized for the production of adhesive, coating materials, and paint because of its excellent physical and chemical properties.[1,2] The latex paints produced from these copolymers exhibited resistance to weathering and long-lasting color.[3]
We have studied the catalytic decarboxylation of biobased itaconic acid, citric acid, and aconitic acid to methacrylic acid (MAA)
We have performed the screening of the active noble metal for the synthesis of MAA from Itaconic acid (IA) (Table 1, entry 1−3)

Summary

INTRODUCTION

The copolymers of styrene (St) and n-butyl acrylate (BA) are important polymeric materials commercially utilized for the production of adhesive, coating materials, and paint because of its excellent physical and chemical properties.[1,2] The latex paints produced from these copolymers exhibited resistance to weathering and long-lasting color.[3]. During the emulsion polymerization process, acrylic acid and methacrylic acid (MAA) are added to enhance their latex properties It can make the copolymer pH resistant, thermal resistant, and improve their mechanical and adhesive properties.[7,8] The presence of the carboxylic group on the outer surface provides stability to the poly(St-co-BA-cocarboxylic acid) copolymer.[9,10] The main disadvantage associated with the use of such carboxylic acids is the source of origin. These monomers are derived from fossilbased sources that are finite in nature.[11] The transition from petrol-based to bio-based coating materials is of general interest to achieve sustainability. Poly(St-co-BA-coMAA) copolymers have been prepared by the radical polymerization of as-synthesized MAA with St and BA
