Preparation and Characterization of Acrylic Pressure-Sensitive Adhesives Crosslinked with UV Radiation-Influence of Monomer Composition on Adhesive Properties

Round 1

Reviewer 1 Report

I read the manuscript entitled “Preparation and characterization of acrylic pressure-sensitive adhesives crosslinked with UV radiation -influence of monomer composition on adhesive properties” prepared by Karolina Mozelewska. The article is pretty interesting but there are some points which need to be addressed before publication:

The abstract must include the goal of the work, and also, it needs to be improved. There are many repetitions.

The introduction could be enhanced as there are parts not connected, in a similar way the main goal needs to be explained.

What is the purity of the reagents?

Please, I think Figure 4 can be improved, the resolution and also the range (to 3250).

What is the error for the results of cohesion at 20 and 70°C? I think error bars must be added. In a similar way the error must be clarified for other experiments.

Reviewer 2 Report

Comments:

1. About the introduction of part 1, the authors make a description about some current developments and advantages of acrylate-based pressure-sensitive adhesives. However, authors do not describe the research situation and problems in these studies. This does not highlight the innovation of the article.
2. There are some issues in figures and tables. For example, in Fig.1, there are no structure of AA monomer in the schematic presentation of the performed syntheses and theoretical structures of the synthesized copolymers. In Table 4, the shrinkage of obtained copolymers in Table 4a and Table 4c are the same, and it is suggested that the authors check the results carefully.
3. In results, there are some descriptions that are inconsistent with the figures. For example, the description of “With the increase of the coat weight, the cohesion decreases (for 30, 60 and 90 g/m² it is maximum -72 h, low at 120 g/m²)” is inconsistent with the 5, and the description of “with an increase in the grammage, the thermal resistance decreases, and with an increase in the dose of UV-C radiation, the thermal resistance rather increases” is inconsistent with the Fig.8.
4. There are some format errors in this paper. For example, in Line 64, the “PSA” appears for the first time in this paper, the authors need to write the full English name here. In Line 133, the “¹ES” should be “ES¹”. In Line 255, the “ Figure 4a” should be “Table 4a”.
5. As for references, only few references are recent five years in this manuscript. The new references must be added to prove the meaning and innovation of the work, and the format of reference should be modified according to the requirement of Materials.

Round 2

Reviewer 1 Report

The authors addressed all the comments. The paper can be published.

Reviewer 2 Report

The acrylate copolymers were synthesized with butyl acrylate (BA), 2-ethylhexyl acrylate (2-EHA), acrylic acid (AA) and 4-acryloyloxy benzophenone (ABP) as raw materials in this manuscript. The tack, peel adhesion, shear strength (cohesion) at 20 and 70℃, SAFT test and shrinkage were studied.

I have carefully examined the revised manuscript. The authors have revised the manuscript according to my comments, and I recommend the manuscript for publication in Materials
