“…In general, base polymers have a huge impact on viscosity and rheology, cohesive and adhesive strength, creep and tack, as well as processing and working temperature [ 39 , 40 , 51 , 52 , 53 ]. Common primary resins used in HMAs include ethylene–vinyl acetate (EVA) [ 38 , 43 , 45 , 49 , 50 , 54 ] polyolefins [ 54 , 55 ], styrenic block copolymers (SBC) [ 56 , 57 ], butyl rubber [ 58 , 59 ], polyamides [ 38 , 60 ], and reactive resins [ 48 , 61 ]. The modification of base polymer properties is obtained by the addition of tackifiers.…”
