2. The composition according to claim 1 , wherein the polymer compound has a weight average molecular weight (M) of about 500 to about 50,000 Da.

3. The composition according to claim 1 , wherein the composition additionally comprises at least one component selected from the group consisting of (i) benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-, methyl ester, (ii) benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-, (iii) methanol and (iv) tin.

4. The composition according to claim 3 comprising less than or equal to 1.1 w/w % of benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-, methyl ester.

5. The composition according to claim 3 comprising less than or equal to 1.1 w/w % benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-.

6. The composition according to claim 3 comprising less than or equal to 1.5 w/w % of a combination of benzenepropanoic acid, 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy- and 3-(2H-benzotriazol-2-yl)-5-(1,1-dimethylethyl)-4-hydroxy-, methyl ester.

7. The composition according to claim 3 comprising less than or equal to 700 ppm tin.

8. The composition according to claim 1 essentially free of tin.

9. The composition according to claim 3 comprising less than 3000 ppm methanol.

10. The composition according to claim 1 having a Gardner Value of 1-8.

11. A cosmetic composition comprising the ultraviolet radiation absorbing polymer composition of claim 1 .

12. The cosmetic composition according to claim 11 , comprising from 0.1 to 50% by weight, based on the total weight of the composition, of the ultraviolet radiation absorbing polymer composition and a cosmetically tolerable adjuvant.

13. The cosmetic composition according to claim 11 or 12 further comprising a UV filter selected from the group consisting of:
