Abstract

Polymer compositions for UV curable primer formulations, as described herein. The primer formulations contain a modifier selected from the following: at least one modifier selected from a) through d) below: a) R1R2C═CR3-(CO)—Z (Formula A), as described herein, b) an acrylate-containing oligomer that has a Mn≤1500 g/mol, and an acid value from 50 to 500 mg KOH/g; c) a random terpolymer comprising, in polymerized form, vinyl chloride, vinyl acetate, and at least one of the following: a hydroxyl-containing alkyl acrylate, a hydroxyl-containing alkyl meth-acrylate, or a combination thereof or d) any combination of a) through c). Such primer formulations are useful for the binding of olefin-based polymer foams.

First claim

What is claimed is:

1. A composition comprising at least the following:
A) at least one modifier selected from a) through d) below:
a) R 1 R 2 C═CR 3 —(CO)—Z (Formula A),
wherein R 1 , R 2 and R 3 are each, independently, selected from the following: H; alkyl; heteroalkyl; aryl; heteroaryl; —C(O)—OH; or —R—C(O)—OH, where R is alkylene;
Z is selected from the following: —OH; —O—R—OH, where R is alkylene; —NR′R″, where R′ and R″ are each independently H or alkyl; —N(H)—R′″OH, where R′″ is alkylene; silane;

 and wherein two or more atoms of Formula A may optionally form a ring structure;
b) an acrylate-containing oligomer that has an Mn≤1500 g/mol, and an acid value from 50 to 500 mg KOH/g;
c) a random terpolymer comprising, in polymerized form, vinyl chloride, vinyl acetate, and at least one of the following: a hydroxyl-containing alkyl acrylate, a hydroxyl-containing alkyl methacrylate, or a combination thereof;
d) or any combination of a) through c);

B) at least one chlorinated olefin-based polymer and/or at least one functionalized chlorinated olefin-based polymer;
C) at least one styrene-based block interpolymer or derivative thereof; and
D) at least one compound selected from the group consisting of the following:

wherein, for Formula D1, R is independently selected from the group consisting of the following; substituted or unsubstituted hydrocarbylenes, and substituted or unsubstituted hetero-hydrocarbylenes, and x is an integer ≥1;
wherein, for Formula D2, R is independently selected from the group consisting of the following; substituted or unsubstituted hydrocarbylenes, and substituted or unsubstituted hetero-hydrocarbylenes, and x≥1.

2. The composition of claim 1 , wherein the composition further comprises at least one photoinitiator.

3. The composition of claim 1 , wherein the weight ratio of component A to the sum weight of components B, C and D, A/(B+C+D), is from 0.10 to 0.75.

4. The composition of claim 1 , wherein the component A is present in an amount from 5 to 35 wt %, based on the weight of the composition.

5. The composition of claim 1 , wherein the component A is a random terpolymer (subcomponent c) that comprises the following properties: i) Mw from 10,000 to 100,000 g/mole; ii) from 70 to 95 wt % vinyl chloride, based on the weight of the terpolymer, iii) from 5 to 15 wt % vinyl acetate, based on the weight of the terpolymer; and iv) from greater than zero to 15 wt %, based on the weight of the terpolymer, of a hydroxyl-containing alkyl acrylate, where alkyl group comprises 1 to 6 carbons, or a hydroxyl-containing alkyl methacrylate where the alkyl group comprises 1 to 6 carbons.

6. The composition of claim 1 , wherein component D is selected from the following: (a) through (l):

7. The composition according to claim 1 , wherein component D) is selected from the group consisting of the following: 1,6 Hexanediol diacrylate (HDDA), tri propylene glycol di-acrylate (TPGDA); dipropylene glycol diacrylate (DPGDA); 1,4-butandiol diacrylate (BDDA); Diethylene glycol diacrylate; Triethylene glycol diacrylate; Neopentyl glycol diacrylate (NPGDA); and Nonanediol Diacrylate (NDDA).

8. The composition according to claim 1 , wherein component B is a chlorinated olefin-based polymer having a chlorine content from 10 to 40 wt %, based on the weight of the chlorinated olefin-based polymer.

9. The composition according to claim 1 , wherein component C) is selected from the group consisting of the following: styrene-ethylene/butylene-styrene block copolymer (SEBS); styrene/butadiene/styrene block copolymer (SBS); and maleic anhydride grafted styrene-ethylene/butylene-styrene block copolymer (SEBS-g-MAH).

10. An article comprising at least one component formed from the composition of claim 1 .
